Serious advice needed on flatworms

todd_nano · 12-24-2001, 06:55 PM

Hello,

It's been a while since I last posted, but my 12 Gallon nano is doing spectacular. Everything is really thriving, and in most cases it is thriving too much. One instance of this is these pesky flatworms, I've tried to photograph them but due to their being so small the pictures would be of little help.

They are flat, about the size of an eraser head mushed into a rectangle, give or take. They are about this wide and tall: | |

They are green/olive with a red dot located towards one end. Then tend to stay on the glass or on the LSB diretly below the front glass. Killing them manually is a lost cause because it is impossible to get them all and they multiply so quickly.

I am looking for a natural predator to eliminate them. A canary blenny was once suggested and it did not touch them. If anybody has any advice I would greatly appreciate it.

Thanks,
Todd

Synchiropus picturatus (Spotted Mandarin) is reportedly one of their natural predators but your tank is too small for one of them.

A Yellow Coris wrass will work...but I'm not sure if your tank is too small for the wrass though. The smallest I've seen those wrass is about 1 1/2".

C. varians(slug) is the only thinh guarrenteed to eat them. but they only have a 2-4 mo lifespan but mine ate all the planeria in 4weeks. maderins wrasses never touched them in my tank. If they did they didn't do much

Thanks for the replies! To be sure, we are talking about a velvet nudibranch right, (Chelidonura varians)? I've trying to find one of these online and the only vendor that I see to be carrying them is Anchofish online. I've previously heard bad things about this outfit, and was wondering if anybody knew of a quality mail order store where I could purchase one of these.

Thanks,
Todd
