my clowns right side fin has gone red (or only noticed its red)?? is this common or a sign of something wrong/damaged???

at the base or the actual fin? i assume you are meaning the pectoral (the flappy one lol)?

will try to get a photo when I come back from whangamata, the whole fin seems to be red, the pectoral flappy one. Its in with an O some large Plecs 3 jewels 1male 2 females I beleive and a female con, they all get along... just had a thought I put a few baby cons in as feeders and they hide under te slate rocks ect I think he might have gone for them and (got himself)

like a blood streaked red? is there any inflammation around the base where it joins the body?

red all the way through and has a couple of bumps know

no pics? sounds bacterial whatever it is, it may have started from a wound or something though.

its really hard to treat big fish (their size makes moving them hard or the water volume of their tank means treating is costly), is he small enough to move still? if so id go with a broard spectrum antibiotic like furan 2 or something similar. im unsure if clowns are med sensitive or not, i know furans fine for plecs etc
