So you may remember the post about the cichlids I recently ordered for my 75g Tanganyikan tank. I posted photos of the newbies except for the Eretmodus cyanostictus, commonly referred to as the Tanganyikan Clown. Finally got a good shot of him yesterday.
Anyway, after nearly three weeks and everyone now settled in, I thought I would give a bit of an update. The Clown is much more gregarious now. He's all over the place most of the time. Of the two Trets, the smaller one is a bit less shy. I haven't vented either one, so it's hard to tell the genders. If I had to guess solely based on behavior, I would say one is a male and one is a female. They do not interact at all and, in fact, pretty much ignore each other. The larger one tends to hide a bit more, but that's not indicative of anything in particular.
The greatest difference can be seen in the Telamatochromis temporalis. If you recall, I said they were quite shy. They have come out of their shell, pun intended. All three of them are very active. I've never kept the species before, so really didn't know what to expect. They're significantly larger than I thought they would be. The largest one is probably at least 2" long. I thought these were the sp. "Temporalis shell," but I'm not so sure. Regardless, they are even more active than the Clown, though they tend to stay nearer the substrate. The Clown gets up into the water column quite a bit.
Of the three new species (Trets, Clown, and temporalis), I would have expected the Trets to be the most adventurous, followed by the Clown. It's actually the very opposite. The Trets are more cautious and more easily spooked. I'm quite surprised at that.
