Chelidonura varians ... flatworm eating nudis

[Len]

Anyone know if these are available anywhere or have been in the recent past? My flatworms are back after my second FWE treatment, so I'm thinking about biological control now. I may try a wrasse (six line or leopard) or mandarin, but I know those are hit and miss.

I've had six lines, canary wrasse, scooter blenny (cheap mandarin) and didn't see them ever go after planaria, as a result, I doubt their effectiveness.

Never tried the velvet nudibranch, but I did keep an eye out, just never could find one.

The nudis still come in from time to time, but they don't do well in a reef tank. The current is hard for them to deal with, and just about any crab seems to like to eat them. They will eat flatworms though.

No crabs in my tank, but I do worry about the current. I'm willing to dial down the vortechs (the return pump has virtually no flow to worry about) if the nudis do the trick.

If I see any I'll let you know.
