What's the longest you guys have brought in a new discus and it goes off food? I'm starting to get concerned.
I've had mine for a little over a week, and he looks perfectly healthy. Moves and swims fine... other fish in the tank (four little clown loaches and 2 balas as long as my index finger, plus a 4 inch ghost knife) do not bother it at all, and the discus is perfectly at ease around them, even the family of clown loaches when they get frisky at feeding time.
I feed glassworms (mosquito larvae), freeze dried bloodworms, two types of flake food, bio blend pellets, and baby shrimp freeze dried. The discus always swims toward the food and seems interetsed, and I've seen him eat, but he only eats about one or two glassworms. As said, the discus ignores the other fish completely (though when I first got the discus, the entire tank was terrified of him--save the BGK--and the four clowns and 2 balas clustered together in a corner like a school).
My book recommended turning the heat up for a new fish. This is done and stays constant at 86-87. Thanks to clown loaches which are two and a half weeks new to the tank, it's also curbing the Ich that always seems to show up when you get a new loach. No sign of Ich on Discus though...
Water parameters are sparkling. Ammonia, nitrite 0, nitrates 5-10. p.H is 7.2.
I'm worried that the discus misses the other brown or blue or whatever discus that was in the sales tank. Stupidly, stupidly, I only bought the one, and the next day when I came back to get the second, someone had already snagged it. I know it's not ideal to keep one discus, but I made a judgment call on it... it was pretty much full grown, in wonderful condition, and I've read of people keeping discus singly and doing fine... in fact, I read one "How to care for discus" article suggesting to keep either 1 discus, 1 mated pair, or a group.
The clerk told me they could have been a mated pair, but who knows. They were about the same size.
Like I said, other than not eating, he's fine (great color, bright yellow golden brown body, bright eyes, alert, etc.).
