About 2 1/2 months ago I brought home a baby Palmas bichir and albino Senegal bichir. I originally had them in a 20 long while I finished cycling my 75 gallon tank, and then moved them over along with my other fish (in my signature). Since they have been in the 75 gallon, my Palmas bichir has been very active, swims all over the place, digs through my gravel and eats well. He has gained about an inch in length. My Albino bichir, though.. Seems to be the same size as when I bought him.. If anything, he looks shorter which i'm sure isn't possible. He doesn't do anything at all. I will notice him in one spot of my tank, and then a few hours later he'll still be there. The few times i've seen him move have been when he goes up for air, which is lightning fast so I know he isn't immobile, but when he comes back down he goes right back to lying somewhere. At feeding time, he'll only eat if I reach in with tweezers and drag a bloodworm or mysis shrimp across his face and then he'll snatch it from me, but after he eats it the most he'll do is look around, turn and flop back down facing another direction. Even when food is inches from him, he seems to not see it. Even though I hardly ever see him eat by himself, he's not skinny at all. He looks perfectly healthy, my main concern is that he isn't growing. My Palmas bichir will come to the front of the tank when i'm nearby, and follows your hand if you put it near the glass, but my Senegal doesn't move at all even if you get within an inch of touching him. I understand that because of inbreeding, a lot of Albino Senegals have genetic problems but this is not what I was expecting. I have counted his spines and he has 9, which from what I have read means he is not short-bodied, but could he just have a slow growth rate? It's not like he *never* eats, if he doesn't try to find food himself I all but stick it in his mouth until he finds it. Could he possibly have dulled senses or is this kind of behavior not all that uncommon? Is he just lazy? Any help would be appreciated.
