Is Mrs Fish any better? I do hope so...I always used to find that a little salt added to the water in a small isolation tank, usually cleared up many fishy ailments...Good luck

No Goldy (all our big fish have names btw) still has the lump. We have checked the nitrate and ph levels and all is ok. I'll take him/her to the the fishy vets tomorrow and see what they say there.... I've noticed one is forming on little babe too, so whatever it is, it's not good
