It's been 2.5 months since I introduced the Ghost Cardinals and I am so glad that I did. They are all round lovely fish. Totally peaceful towards each other and the rest of the livestock, shoal together most of the time and eat frozen food with enthusiasm. They are also really, really pretty fish, my photos don't do them justice at all. The icing on the cake for me however, is that they've now started spawning.
On the 4th December 2020 I noticed that one of the cardinals had stopped feeding, his jaw looked distended and a different shape to the remaining four fish. I hoped that this was an indication that he was carrying eggs rather than being sick. He resumed feeding again after about 5 days I think, there was some disruption to the tank at the time so maybe he was too stressed or inexperienced to carry them to full term.
On the 18th December, during a water change, I happened to notice two of the fish were separate from the rest. I glanced away for a moment and when I looked back again I caught one of them in the act of taking up an egg mass in to his mouth. I have previously observed Red Spot Cardinalfish spawning during a water change (in the Reefer 170), I wonder if the pumps being switched off is a trigger for the female to release eggs, perhaps it's easier (safer?) for the male to pick them up when he's not blasted by flow?
I am yet to witness any babies. Perhaps the fry are released late at night or maybe he hasn't reached the point where he's felt confident/happy enough to carry them to full term.
This week that he's carrying once again, maybe I'll be lucky enough to spot some babies this time...
I've finally managed to capture a half decent photo of Mr Fantastic the Tigertail cucumber. He's rarely visible during the day but after lights out he can often be found stretching out on to the sand to feed. I have tried on a few occasions to take a photo but he's amazingly sensitive to light, one brief flash from the camera and he's gone. This time I set the camera to the smallest aperture (f32), manually focused the lens (a bit tricky in the dark), readied the flash and crossed my fingers. Fortunately it didn't turn out too bad.
He's been with me for almost 6 months now, I assume he's finding enough food to eat because he's never strayed from the right-hand side of the tank and he's significantly bigger now. I couldn't tell you exactly how much bigger he is because he never shows his rear end. Whenever he pops out to feed he always has his bum anchored underneath the rocks for safety. This is totally fine by me as I don't want him climbing the glass and getting anywhere near the pumps.
Ming the Pom Pom crab was also out and about so I took the opportunity to snap a picture of him too. He's such a fascinating and cool looking crab.
I've noticed recently that the two small gorgonian frags added at the end of September 2020 seem to have developed some strange elongated polyp tips which look a lot like sweeper tentacles. As far as I was aware gorgonians didn't produce sweeper tentacles but according to 'The Reef Aquarium, Vol 2' by Sprung and Delbeek some species actually can (Erythropodium caribaeorum and Muriceopsis flavida). So is this what I'm seeing here and if so why is it producing them? There is no obvious encroaching coral so I am currently at a bit of a loss. I'll have to keep watching them carefully to see how it develops.
