Brown Mold on zoos

[bunzaroo]

Lately I have some colonies of zoos that are not opening up. I noticed that they have a brown moldlike growth on them. I don't have any pics yet. They were doig great a month ago.I have changed nothing in the tank. Any clues?

Extra lighting, increased temps? lack of clean up crew getting to them...

Look into Zoa Pox, as this sounds alot like you are describing.

If it is, Furan II dips can work wonders.

you probably have fungus....

SOft toothbrush, gently scrub them, and you can use Furan2 on them as well. It takes out gram positive and Gram negative bacteria.
