spotted dwarf puffers

[tropical_adam]

After you guys helped me set up my 20 gallon community, i have decided to go for something a bit different. I have approx a 2.5 foot tank with 3 puffers, 2 corries, 2 fairy gobies and 2 glasss catfish. All seem to be gettin on fine (No bullying). But 2 of my puffers seem to change coulour quite frequently, Sometime darker, sometimes lighter. oneof them had a small hook like thing growing between its eyes just further down its head, it also seemed to have little oxygen bubbles clinging to it and some small particles of dirt from the tank.

Since adding an anti fungus and finrot treatment the growth thing seems to of gone.

Any ideas what this could of been?

Only i think it killed one of my puffers before

Thanks on advance for any help

For one thing, as those puffers get older they will probably kill the other fish in the tank. They get grumpier with age. I am assuming they are dwarf puffers or else they are going to get way to big for that tank. They may have been some sort of worm or parasite that clinged to your puffers.
