I have a small bowfin that I got about a week ago He is in 150 gallon tank with Tetras and a bunch sixteen 4 to five inch clown loaches,I thing my blue garamie might be the reason,but he does not chase to the point were a actually does any damage the bow fin can swim to the bottom when he wants and eats every time I feed he, is about three and a half inches long and I do not think that he has any kind of bloat, so do any of you experience that behaver
