Hi everyone about 5 or 6 months ago I got two baby Senegals. They are kept in a 55 til they are big enough to need the 125. Recently Iv been noticing one of them has grown nice and thick and the other looks very emancipated and lethargic which is strange because i always watch to make sure everyone eats so i currently have him quarantined in his own tank ( 15 gal as he is only 4 inches long ) over the past couple days Iv been lightly feeding as to not make the issue worse and he has been eating what I put in there. Is this an issue of him needing to get his strength back and weight back so he can compete for food again or is there another possibility I’m missing ?
