I think my male siamese fighting fish is dying.
I've checked my water levels,
Nitrate: 0
Nitrite: 0
Ammonia: 0
And pH: 7.5-8.0 (grr, i can never be too sure)
It started, i'd say... this morning. (He was fine last night). He's on the bottom laying lazily on the gravel (literally on his side), breathing heavily, then suddenly swimming up for breath then just, flopping himself back down on the gravel. He seems to swim up for breath right at the last minute... But other than that he was on his side, just laying there. Seeing as his a semi-active Betta that i've never had problems with, i'm concerned.
I do water changed every other day, like i said, nothing has changed in the tank... and he has been fine until this morning.
I don't see whats wrong.
can anyone help?
PS: May i add, he is extrememly peaceful, as with all my other fish... so i know no fight occured (plus, no marks)
