Look at the pictures and tell me if this is
a- Fin rot (pin holes)
, it appeared suddenly not more than a few hours ago
, fins are long and heavy it could be
c- Damage from decor,
possible too, however it may look a bit too clean for a decor damage type wound
, he flares AT LOT, more than any other betta I've seen so far
His tank is a 4G, he will have live plants on Tuesday, and the bright gravel will be replaced with sand. As you can see the wounds are clean and in a specific concentrated area. I'm leaning towards A
. But I want your feedback as well.
So far keeping water clean and warm.
In case of fin rot, which I think it could be, how often should water be changed in a 4g tank? Though it also looks like tailbiting, in that case what could I do to distract his agression?
(It's weird because I performed a 100% water change yesterday. Because I added him to his 4g)
