I have a 75 gallon tank. I have an albino frog who eats my goldfish quickly. What types of fish can I put in with him? Sharks? Hi! I have a 36 gal tank with a large veiltail goldfish,a large what I think is a marbled angelfish, and a new bala shark fish. I have had the tank for about 3 months, it is an upgrade from a 10 gal that I had about for about a year. The angelfish was the size of a silver dollar when I got it and now it is as big as my palm. My problem is my plecos..I’ve had I think 3 die recently. I don’t understand why?! All my other fish appear to be healthy. I don’t know if I want to keep trying with them. Is there anything that I can get to help keep the tank clean that is maybe more hardy and can live with the types of fish that I have? Thank you in advance!
