Recently my sister brought back her betta fish that she had been keeping at school for her science project to see how animals act in without human help. He had been kept in a 2 liter bottle with filthy water and hasn't been fed in over 8 months. When he came home I went straight to work and set him up at 10 gallon tank with a heater, filter, decor, etc. He has been very healthy and has even built a bubble nest. Whenever i walk past his tank he always comes to the surface looking for treats. But anyways, my sister has just informed me that she has two other betta fish coming home that she saved from being dumped down the drain. I don't know what to do. I refuse
to keep them in anything smaller than a 2.5 gallon tank and w/out a heater. My parents are the issue. They don't really want the space or money spent on fish. I do have a 3 gallon but it's a joke. They tank leaks sometimes, the filter is busted, the light is broken, and it almost impossible to change the water without electrocuting you and your fish. What would you do?
