Hi all,
Tank has been running for over a year - decent
ammonia/
nitrite/nitrates a bit high,
pH 6.6, temp 78F.
Firemouth, Jack Dempsey - smaller
JD, GOurami, and tiger barb (I know not a good mix but so far haven't killed each other - this set of fish stick together and collectively attack anything else I put in the tank - go figure).
27gal hex - penguin 500 filter.
My firemouth has this odd pink spot along both sides of its dorsal fin. I'm hoping its not fin rot, but in any case the gourami does seem to be nipping at it (I saw him do it at least twice). Its sort of a growth and looks like what I would expect a fish scab to look like - I can get pics later tonight.
Any ideas what if anything I should do?
