Fish Fanatic
Hi All
I recently noticed my betta split his rear tail which is slowly healing but the tips of his fins is becoming clear and look a little tattered and over the past few days hes becoming aggressive towards the 3 tetras I have (not attacking them but he flares his fins out and gills open up to make himself look bigger, never done that before
) hes still quite active swimming around building a bubble nest and doing what fish generally do best 
could this be fin rot? I know tetras are fin nippers but I have never had a problem since they where put in the tank and they seemed to all get along until the past few days could this be the tetras nipping at his fins?
