Hi and thanks to all reading....I got two albino tiger barbs not knowing anything about them
and got a little one gallon goldfish starter bowl
they both died so when i figured out they needed a filter and a heater i went out and bought a ten gallon tank and got three new fish(albino tiger barbs)and before i knew it they they were all attacking each other eventualy i took them back and got 3 cardinal tetras
two got stuck to the filter and the other one is in the tank alone.How do i stop them from getting stuck and should i bother with that type of fish???
