Hello, I am new here and I have been worried about my 2 year old male betta. He is currently in a 2o gallon tall tank, live and fake plants with many decorations. He has been clamping his fins and there appear to be tears. I am almost 100% sure it is not fin rot, as I have seen fin rot before. He is getting old and it takes him a while to spot his food and other than the clamped fins he appears to be fine. The tank is heated, filtered and all water parameters appear to be fine. I have a cycled 3 gallon Aqua Farm tank set up in case he gets sick, should I move him there? Any responses will be greatly appreciated.
