i think my betta has fin rot. his fins look raggy and at the base of his fins it looks like it start to turn red (he is a blue betta) his fins looked raggy when i got him but there was no red at the base and i just seen it today. so i think its fin rot
how would go on treating this?
and does fin rot cause a fish him not to eat? he has barely ate anything since i got him (jan 27th)
