I have experience with E variatum and E osburni. Wild fish as usual will
need careful attention to feeding. They will decline if kept in a
food-competitive setup. Temp is probably not a big deal, but warmth will
increase metabolism and food requirements and will likely shorten their
lifespan. E variatum seems to fade quite a bit from breeding color. E
osburni seems to retain its color well. I have osburni on freeze-dried
foods. The older fish I had died off. The ones that were younger
(smaller) at the time of collecting are doing well. I have a small number
of fry and plan to produce more. The initial spawning was by
wild-conditioned fish at the natural spawning time. That is virtually fool
proof. Don't know yet about captive conditioning. Check back with me in a
month or two!
