While cleaning old water out of his tank, my half-moon beta jumped into the sink and fell down the disposal! I was able to rescue him after being in there for a minute, maybe a bit longer, but he is badly damaged. A large piece of his long beautiful tail came off! I put him back into his clean tank and he has not been moving too much. I put a little food in the tank for him and he swam around to get it a few times but he is swimming very choppily compared to before. I am very worried about my baby! I am glad to see him swimming around but what is the likelihood he will survive? Any tips to help him heal?
