They gave me the first 3 fish to cycle my tank and then I went back after like 4 months and got the 2 algae eaters. They told me that they would all get along great and they are tropical fish tank fish. I had a 55 gallon tank but had to move them to a 10 gallon tank bc my 55 gallon broke. It wasn’t that I didn’t know what they were, I looked at pics and thought that they were danio, but wasn’t sure. I simply asked the question bc I want to do well with them. I have another tank I’m going to go get tomorrow and it will be similar to my 55 gallon. I believe that all the dimensions are the same. I believe for filtration I have the marine land bio wheel. And I have a water heater I keep at 75 degrees.
