A friend of mine sold his tanks because he's getting the heck out of his parent's house (smart guy) and can't keep lager tanks where he'll be living. Given that, I ended up with a 6" Clown Knife. Yes, I'm aware these guys get large. I'm still not sure if he's wort keeping and investing in a larger tank, but for now he's sharing a 55 with a 3.5" female Jack Dempsey
, a 3.5" female Texas, and a 1" convict.
Anyway, I've had my knife for about a week and he's been extremely
shy. At first he wouldn't come out unless it was pitch black. I have him in a finished basement with no windows, so it does get that dark with the lights out. The last few days, however, he hasn't seemed to have moved from underneath a log ornament I have. He also doesn't seem to be responding to food, at least while I'm around. I've been trying frozen bloodworms , frozen brine shrimp, and live night crawlers before lights out. As far as I've seen, even with just enough light in the room to make him out in the tank, he hasn't even taken a nip at any of it. The worms were gone in the morning, though my other fish were all over them as soon as I dropped them in. I don't know how they could have gotten all of them down by themselves, however!
For those who have owned this species, what would you suggest about the eating problem? Should I just assume he's not starving himself? Do they ever become more outgoing? It's hard to justify keeping such a potentially large fish when you never get to see it doing its thing, or even moving for that matter!
