I've asked a question on here about this before, but I never really got any help. We have had 'Bubbles' the Betta fish for a year now. When we got him, we were still very new to fish. His tank was not ready when we got him (we trusted the advice of the "certified aquatic" whatever person at the pet store. Big mistake!) Anyway, he is in a 10 gallon, filtered, heated aquarium. For the last six (? Or so) months he has just been floating on his side at the top of the tank. He doesn't move unless you try and touch him with a net or stir the water with your finger near him. Then he will either swim (still floating on his side) a tiny bit away, or try and swim down (he is unable). Recently the water is starting to smell gross (kinda like a bad ocean if that makes sense) and get (white) cloudy. His fins are looking frayed. I don't know what to do. I just did like an 80% water change. Please help. It kills me to see him like this. The only advice I have been given is to "humanely euthanize" him with clove oil. Obviously I want to try to get him better...But I'm really lost. that's him floating in the bowl as we did a water change. Please help!
