Zoo's in trouble?

[rolxism]

Everything else in my tank is perfect, these were great i've had them for prolly 3 weeks. All of a sudden there looks like theres stuff all over it and looking generally not good. Any ideas?

it is hard to see in the pic but if it is a white coating i just had that happen. i lost and entire colony that was about 6 inches by 8 inches. good luck...i was able to frag off three polyps before they were infected.

cant really tell from the picture. are the brown button polyps??? how much flow do you have on them?? you might try a fresh water drip, and higher flow.
Also do a search on zoo pox.
