Egg-sac-tly!

6/12/2020

0 Comments

 
This morning when I was cleaning the glass I discovered a strange white blob stuck to the right-hand glass panel. On further examination I realised a lot more of these strange blobs were scattered along the length of the back glass. My first thought was that they were more limpets (because I have plenty of those already) but when viewed from the side these blobs lacked the pointy shape characteristic of limpets. When viewed through a magnifying glass it became clear that they were in fact egg sacs. I hadn't seen this particular type of egg sac in my tank before so they must have been laid by something recently added. Three Nerita sp. snails were introduced on the 23rd October 2020 and a quick search of the internet confirmed that these snails were probably responsible for the eggs. Unfortunately is unlikely that I will see baby snails develop in the future as the larva require sufficient planktonic food for survival. Shame!

The beast, aka Pablo the Turbo snail

Pablo has been with me since the 27th December 2016 and still appears to be going strong. He's one of the most hard working members of my clean up crew.

Here he is January 2017 in the Reefer 170:

And here he is July 2020 in the D-D Reef-pro 1200.

He works tirelessly cleaning the rocks/glass and pumps of algae. As you can see he's a lot bigger now (clearly I have plenty of algae to feed him). He's completely covered with coralline algae and is probably 90% responsible for seeding the new tank.

Life at last

Once the cycle was complete (fingers crossed it was) I switched on the light (I say light because at that time I only had the one unit up and running at that time) to encourage the growth of diatoms. By day 34 the tank looked like this:

I decided it was time to add some clean up crew and a fish. I'd spent a lot of time thinking about what to add as a first fish and I emailed several shops asking about special ordering fish but only one bothered to reply to my query, very disappointing. In the end I decided to go with whatever was available in the shops. We visited two different places and I ended up with 5 black foot Trochus, 5 teeny tiny hermits, a conch and a Sunburst (aka Fathead) Anthias. The anthias settled in a treat and is a really lovely fish. To begin with he hung out at the darker end of the tank (the side without the light) which is pretty much as I expected but after a week or so began exploring the whole tank. The snails and crabs got to work on the algae straight away, I did sadly lose one of the Trochus after 11 days but the rest were fine.

Since the fish and CUC seemed to be doing fine I decided to try transferring over a few tester corals from the Reefer. I decided to move over a couple of the gorgonians first, both have been severely shaded by other corals for a long time and deserved a break plus if they didn't make it I wouldn't be overly upset about it. Anyway as it happened they were totally fine, bulletproof it seems, and are loving basking in some good light again. The Plexaurella was quite bleached (and a bit deformed too) but is looking much happier now. The Muricea is hidden at the back of the tank but is also looking much improved. I know that gorgonians are not everyones cup of tea but I really like how they sway about in the current.

Once it became clear that the gorgonians were not going to keel over and die I decided to press on with a few more transfers especially since the second lighting unit had arrived and been hung. I was also starting to feel a bit of pressure by the rest of the family to just get it done already. I keep having to remind them that slow and steady wins the race.  This time I chose to move a couple of more accessible corals, ie the ones not actually welded to the rockwork. The Heliofungia (plus shrimp) and, gulp, the Scolymia. I was particularly nervous about moving the Heliofungia in case Milo, the resident shrimp, decided to jump off and vanish into the rock-work or be eaten by a hungry fish! I needn't have worried Milo was not going to leave his home no matter what, wherever the coral went he was determined to go too, phew!

I wouldn't say that the Helio or Scoly are entirely happy in their new home, they are not as expanded as they were in the old tank. I'm hoping that they are just adjusting to the different lighting and/or the reduced nutrient levels. I hope that they will settle given a bit of time.

One step forward one step backward...

17/8/2018

0 Comments

 
It occurred to me after my last update regarding the continuing red bug issue that there was one pest I hadn't actually seen in the tank for a while and that was pyramid snails. For months and months I religiously siphoned out as many of the tiny parasitic snails that I could find, I literally removed hundreds of them without any obvious dent in their population. Naturally this got old very fast and as the months went by and my hardworking clean-up crew (Trochus & Turbo snails etc) and clam looked fine I became less vigilant. I would still remove any that I saw attached to the snails but I no longer actively seeked them out. Today though I've searched the tank most thoroughly with a magnifying glass and cannot find any evidence of a single pyramid snail. That's not to say that they aren't still present in the tank but considering how many there were at one point I take it to be a positive sign. Perhaps one of the fish has finally found a taste for them, the most obvious candidate being the Yellow wrasse but I have never seen her (now him) show any interest in eating them even when faced with one crawling up the glass in front of her face.

So that's the step forward, now for the backward step. Since the demise of some of my Acropora I have been faced with the issue of what to do with their dead skeletons. I fragged off as much as I could but that still left a goodly amount of encrusted base on the rocks. Sadly these have now become a magnet for hair algae. Normally the snails would have made short work of this algae before it had chance to establish but they find it quite hard to navigate their way round the rockwork these days due to the fact that there are lots of other corals in the way, in fact I hardly ever see the Trochus/Turbo/Ceriths on the rocks at all now, they just spend all their time cruising round the glass. Since this algae is growing ever longer by the day and starting to spread I need to formulate a battle plan asap.

That's it for now I'll sign off with an updated video for your viewing pleasure.

Utter Chaos and CUC.

13/5/2017

There's one zoanthid morph that I've been saving a spot for in my tank but have never seen it for sale in an aquarium shop or via my favourite online supplier so I decided to give E-bay a whirl instead. I ordered two polyps of the "Utter Chaos" zoas, they arrived promptly and were in great condition, I was very pleased (and relieved) with my purchase. I did treat the polyps to a dip in Reef Primer just in case there were any unpleasant hitchhikers, it seemed unlikely on such a small frag disc but as I didn't know the source tank I decided it was not worth the risk. I can see why these zoanthids are so popular, the fluorescent orange colour really 'pops' under the blue LEDs. I roughly chopped down the frag disc as much as possible and hope the remainder will be grown over and hidden asap. I hate frag discs on show in the DT!

I also added a few more snails today to boost my clean up crew as I've noticed that the resident crew aren't quite managing to keep the algae growth in check, not unsurprising now that I am feeding the tank more. So a big welcome to Laurel, Hardy, Eric & Ernie the Trochus snails and Del Boy & Rodney the Ceriths.

The mysterious moving disc thing!

17/3/2017

0 Comments

 
On the 31st December 2016 I introduced Zoanthus sp. #1 to the tank. On the rock along with the zoas came a mystery disc thing that I identified as a foraminifera called Marginopora vertebralis (see here). For a couple of months nothing changed and then suddenly it vanished. I assumed that it had died and had fallen off the rock or had been knocked off by a snail or hermit crab. The following day I discovered it just behind the zoa rock. A few days later however it was in a different spot, OK, so the hermits or snails must have been moving it during their never ending rock cleaning duties. But then a few days after that it was in yet another spot and no way could it have been placed there by a crab or snail unless I have very, very clever snails/hermits. During the next two days I paid extra attention to the foram and lo and behold it was moving around the rock, all be it very slowly, of its own accord. Who knew it could do that?? I certainly didn't!

I have since discovered that foraminifera can move about with slender pseudopodia, or extensions of cytoplasm, the living matter of the cell, which stream through an opening in the test known as the aperture; in porous tests, the pseudopodia also emerge through the pores.

Please see the link below for more details:

This thing is seriously cool!

Who says conchs only stick to the sand! For the time being Lurch manages to get himself up on the left rock pile (straight up the front of the rocks) and half way up the tank back in search of a tasty rasp of algae.

Whitecap woes...again!

8/3/2017

Things have been pretty settled on the fish front recently but today that all changed, trouble brewing on the goby front. This morning I discovered both the T. nudus gobies sitting right outside the pistol shrimp's main burrow entrance, I've not seen this behaviour before. As the day progressed I actually observed them popping in and out of all the shrimp's burrow entrances/exits, something was certainly amiss here! There was no sign of the pistol shrimp or his Whitecap partner but they've gone missing before so I was not overly worried.  That was until the afternoon, when Gordon the Whitecap goby suddenly popped right out of a hole in front of me. I mean the whole fish, not just the head but the whole body and tail too, I would have been beyond excited if it were not for the fact that he'd been chased out of the hole by one of the nudus gobies. What the...?! Where was his pistol shrimp buddy?? The Whitecap is such a timid fish, he's completely lost without his pistol pal. The lights are off now and he's been chased out on to the sand again. This is not good and I'm seriously worried about the whereabouts of the pistol shrimp. Has he died, perhaps through an unsuccessful moulting? If that's the case then I doubt Gordon will survive long without him. I really hope there's another explanation to the shrimp's absence and that he'll resurface again very soon.

On a lighter note I discovered two Stomatella sp. snails cruising about the tank in the last couple of days. I spotted one on the shell of the T. crocea clam when it was introduced but obviously there must have been two. Some good freebie hitchhikers at last!

Annoying resurfacing.

Well my wonderful view of the Whitecap goby and pistol shrimp partner has been somewhat short-lived. Lurch the conch came bulldozing over their newly constructed burrow this morning and proceeded to fill it in whilst performing his routine clean-up duties. Normally I'm thrilled to see him cruising around keeping the sand clean looking but not today. Doesn't he realise that area is now off limits? I'm betting the shrimp will be burrowing somewhere else tonight, somewhere that I can't see I'm sure. :o(

Talking of clean-up duties my eldest recorded a time-lapse video of the tank with his GoPro Hero4. At that time the tank just contained snails and a couple of hermits. I feel exhausted just from watching how busy the 'crew' are, they work so hard.

A few days away

31/12/2016

I had to leave the tank in the capable hands of my eldest son for three days over the Christmas period whilst I was away visiting the in-laws. Amazingly everything survived the ordeal, lol, although the squat lobster is currently MIA. I am hoping that he is in hiding following the shedding of his exoskeleton but equally he may have passed on. I will be very sad indeed if he has died.

I really need to get my dosing regimen sorted out. The alkalinity dropped as I wasn't dosing which is somewhat unexpected since there are no corals in the tank to suck up the calcium and yet the calcium and magnesium levels remained stable.

As predicted the growth of algae (interestingly on the live rock only and not on the sand) has increased with the addition of the new Mitras light so to keep on top of it just before I went away I decided to add some more CUC.  One more small Black foot Trochus was introduced along with a Mexican Turbo snail for added variety. The Turbo snail (named Pablo) has done a wonderful job eating the furry looking algae that has started to cover the well lit areas of live rock.
