    We were given a tank with fish. There are probably 30-40 guppies and 2 tetra, but there are at least 27 plecos that are adults. Since getting the tank, they are breeding and we have 6 babies. Can having this many plecos cause trouble for the other fish? Some guppies have died and we were going to get more fish but I've never seen a tank with so many and now we are getting hairy green algae on the plants. What to do?
