Hi Oldfishlady, thanks for your reply :) He is the only fish in the tank and just silk plants and nothing sharp. I will try to attach a pic for you as I took one of the damage. Yes, killing all bacteria was my main concern, readings are good for ph 6.5 and 0 nitrites and very low reading for nitrates, didn't have an amonia kit but got one today which read very low somewhere between 0-0.1 so the kit says to add stabilizer to speed up bacteria for cycling...so I think that's what I should do?? Yes, did take the carbon out for the meds...have been doing 25% changes every second day with the meds...water has film on the top and sort of foamy...hmmm...from the antibiotics I'm presuming? Have put a new carbon filter in today. I know the enviroment can damage their fins but the hole progressed downward to a split...ok...could still be stress...but the edges were fraying and a small piece came off...so went with fin rot....I think he's doing fine....fin looks the same but no worse...I'm home these days so we stare at each other a lot..
He's a entertaining boy...he likes to play peek a boo...and very interactive...I think he's very happy to have the space and the warmth...thanks for you help and if you have any more comments please send. Thanks a bunch!
