Hi one of my puffers (colomesus) has suddenly developed a red tail. Am I right that this is usually related to bacterial infections? I have checked water and no nitrite or ammonia. Only changed the water a few days ago. Swimming around happily just the red tail. The temperature of the water was a little high, must be from the warmth in the room as its been hot. Could this have caused it? I also have another one in the tank who is fine, and a bristlenose plec who seems fine too. 100 litre tank.
I have esha 2000. Should I use this? Or any other suggestions?
I posted on the emergency board a few weeks ago about my 5 yr old shubunkin who is lying at the bottom of the pond and cannot swim. I have done many many water changes, used esha 2000 for 3 days and still he is no better. The water is all normal now, no ammonia, nitrite or nitrate and pH is 7.5.
He is very bloated. Is there anything else I can try or do I need to put him out of his misery? Don't want him to suffer but don't want to give up without trying everything I can first.
