Hey do you think you could give me some advice on this guy. How big is yours? I have a 12inch one... I'm scared to put him in my bigger tank because I have smaller fish in there, some 4-13 inch bichirs, 2-8 inch datnoids, the smaller bichirs and datnoids... will they be safe with him? Mine only eats hikari massivore, alage pellets, and chopped up earthworms. Please let me know, would kindly appreciate the advice, thanks.
