Me and my wife went on a betta shopping spree yesterday and got some gorgeous betta's
They are all males and we have 2 of them in each tank (divided ofcourse) for now untill we know if they'll survive the 14 day guarantee.
Once they do we'll get them their own big tanks to flourish in.
So one of our pretty male boys "Bahamut" seemed to be doing great when we bought him.
We put him in his tank after cleaning letting the water reach the same temp as the water in the tank.
Fed him 2/3 pellets since we had no clue if he had been fed in the store at all. (Petco)
Now yesterday evening and still this morning he has this weird bulge just infront of his tail fin.
it seems to be more defined on his right flank than it is on his left.
I took some pictures of him in different states of his behaviour.
Bahamut flaring at the other resident
Bahamut flaring calmly
Poor bahamut seems to be floating upwards and when he flares he goes sideways.
Does anyone have a clue how to help this poor soul?
