LOL, the drop-eye debate :lol:
I've read a lot about drop-eye on various sites and there are almost as many theories as there are Aro keepers out there.
Its interesting though, that drop-eye is most common in Silvers and Asians, the two species that are farm-bred (Silvers) and heavily in-bred (Asians). It very, very rarely shows up in Blacks and Jardini's, both species that are mostly still wild-caught or only very occasionally tank-bred. Of course, environmental factors are going to have an impact, but I've seen posts by ppl who've had Silvers and Blacks in the same tank, same food, same water....... the Silver will get drop-eye but the Black will not :-?
It's interesting what you say about yours not being fed feeders and being safe with other fish, David. I got my Silver only a few months back, he was with Mystic for several months before that. To my knowledge, he's never been fed feeder fish before. Just the other day, Tye dropped off some of her accidental hybrids for my Clown Knife to dispose of, and the Aro went absolutely crazy, tearing around the tank trying to catch them. Even though he'd never been fed feeders before, he knew exactly what those little fish were. Instinct is truely quite amazing 8)
