so i have noticed that over the last month a small colony of magician zoas has been looking a little pale in color. i though maybe it was the water but i have my water in tiop top shape now and they still looks kinda weird and faded. in the last few days i noticed them not open at all. tonight before i was going to bed, i looked into the tank with a flash light and saw a bunch of large adult amphipods eating a few heads. i am sure they are eating it because i watched one of the fat buggers sit they and chomp on it like he didnt care about the super bright flash light on him. i think i saw him flip me off too!

the type of amphipods i am refering to is the big guys that kinda look like a dog flee or something. they came be about 2 or 3 mm long but stay kinda curled up most of the time, kinda like a shrimp. the pics of them are pretty common on the web.

so my though was i need a wrasse or a manderin goby stat. i have no preditors of them in my tank right now because... well i wanted their numbers to grow so i could then get one... lol i guess its time.

anyone else have this happen?

I've got those buggers in my tank also. My royal gramma sucked a bunch down but they no longer show thier face during daylight hours. At dusk/night, I see my bangai cardinal hunting them down.

I have those in all of my tanks and have some zoas (not the exotic kind though) and they have never touched mine. Perhaps they only like the expensive ones LOL

I've got those with lots of zoas and palys. Maybe the polyps were on their way out for some other reason and these guys saw that as dinner?

You have other colonies that look fine right?

i just noticed my blue zoas are looking like crap on half the colony. but i have a ton of other zoa's that are fine. weird. i though maybe the population of the little buggers just got to high for the food thats in there. i run a clean tank. not any algae to be had because its super clean and the fuge has a big ball of cheato.

Melanurus wrasse... I had zoa eating nudis... a dose of flatworm exit to kill the adults, then the wrasse to eat them as they hatched... no more problems!
