Blue Velvet Nudiranch

[Psycho graphic]

I have an out break of Flatworms. It sarted with small white ones, about 1/8". I read they were a result of excess nutrients and would go away. I have a 30 gallon with a 10 gallon fuge. I have a ton of snails, a handful of hermits, all soft corals and no fish. I feed the tank a small amount of freeze dried Phyto once a week, sometimes every 2 weeks. My flow rate is no where what it should be, about 200GPH. The white flatworms stayed mostly on the glass, they went away pretty quickly and where replaced with red F/W's, same size and shape but these guys have colonized one rock about 8" and they just about completely cover it. There are some stragglers appearing throughout the tank now.

Ok, if I have'nt bored you yet, it's time for my question. How much do Blue Velvets eat a day?

I would much rather find a predator for the F/W's and not have to resort to using F/W Exit. I know BVN's only eat flatworms, so before I get one I would like to have someone to pass it on to if it would run out of F/W's in my tank.

if they are on one rock is it possible to remove that rock? then you could just siphon the rest out

It would be a real PITA to get the rock out.

It's hit or miss that a Blue Velvet Nudiranch will eat them or enough to get rid of them, they also have a short life span. It's better to siphon them out, like Jon, said. Just keep doing over a # of days until you get most of them out. You may want to try it, the Blue Velvet Nudiranch, or one of the smaller wrasses that eat them.

I had an outbreak of the red FW's over a year ago. It's not physically possible to have a predator eliminate them. There are places between rocks that the nudibranch or wrasse cannot get to. So when you don't see any left and you remove the nudibranch, they'll just multiply again.

I have found that the only way to completely eradicate them is with FWE. I will say that I haven't tried every other remedy out there. But FWE gets into all the nooks and crannies whereas a predator can't.

If you want to know the FWE treatment process that I used (completely successful) LMK. I've treated every coral that I put in my tank since then with FWE for preventative measures. I have not had a reoccurance since.
