Hello I have had my betta for around 8 months I believe but am not sure. He was in a 1g (I know i know) but is know in a 10 gallon with 5 endlers. He is non aggressive and the endlers dont nip his fins. He had fin rot but is healing/healed (has a little bit to go but has been healing fast) Tank is 76 degrees ph 7.8-7.4 0 ammonia 0 nitrite. The base of his fins are discolored and it is spreading around. I was temporarily concerned about dropsy but I believe he does NOT have it. Can anyone tell me what is happening with his fins? He appears to have a few scales missing on one side. Please tell me if there is something I can do or if this is normal.
