Hello, so i have had a betta in my 17gal tank now for a month. The tank has the betta,some small loaches two dwarf frogs and a female gbr cichlid. Everything has been fine until today when i came to the tank and saw the gbr chasing the betta and ripping its fins. I removed the gbr from the tank and the betta has spent the rest of the day hiding behind a plant. It has now calmed down and came out to eat but its fins are almost destroyed. Will they heal on their own? I was thinking of maby trimming of the shredded parts of the fins so they could grow back properly. What should I do?
