well everyone my neons have wiped out everything in my tank including my glow lights cause they had Columnaris gees it is so deadly but any way I will stay away from neons now.

I have 3 honey dwarf gouamis in there still survive just want to get ideas from you guys I will just keep it as a gouami tank as I have tetras in the other tank. I want do any thing till January. Now should I put more honey dwarfs in there and keep it all yellow or put red gouamis in there to mix the color up it's only a 60 Litre tank .

Your gourami's will be carrying the disease, if they don't die, they will almost certainly infect anything else in the tank.

have you treated the whole tank?

I suggest more honey dwarfs, and then adding some rasbora, like harlequins or something.

Cheers Dennis yes I treated the tank with wonder tonic all week and now I put the carbon sponge in the filter.

Columnaris is something that is there anyway, it gets a toe-hold if the fishes' immunity is weakened. It isn't really carried, but it may still be lurking in higher numbers than usual.

Try and figure out what weakened the fish to begin with, improve maintenance and get the remaining fish as healthy as possible. Then think about restocking.
