I recently discovered some zoa-eating nudis on a zoo colony in my tank. Easily the coolest looking pests I've come across... slow-moving, color-changing zoos!
I think the last zoa frag I added to the tank was probably back in June of last year, and I think the last frag of any coral I added was August/September, so I've likely had them for at least 5-6 months.
My colonies all have been growing at a rate I'm happy with, but it would stand to reason that I could be seeing even more growth if I were to completely eradicate them.
It wouldn't be difficult to remove 75% of my zoo colonies, but the other 25% aren't really possible at this point. (It appears that melafix, iodine, coral rx, FW, and h202 are all possible options)
I do have a leopard wrasse (m. meleagris), and I've read that they may or may not feed on the nudis. That may be part of the reason I haven't noticed them until now.
I have 2 main questions:
1) If I'm not able to remove all of my zoos, is it possible to eradicate them, or is it highly likely there are eggs/nudis on all my colonies?
2) If I haven't noticed eaten/missing zoos, is it likely that my leopard is keeping them in check and is there great risk in not doing anything?
The only posts I've read are zoa-dominated tanks without any biological controls, and it seems to be a massive problem without an easy solution.
Mine doesn't appear to be on that level, but I made that mistake in reasoning with bubble algae once and that turned into a nightmare.
I kinda like the idea of a natural food source for the leopard if there isn't a risk of them exploding in numbers and quickly wiping out colonies.
penny for your thoughts?
