LF - Berghia Nudibranchs

[DACJ]

Was wondering if anyone knows where to lay my hands on a couple of them, or anyone in vancouver has a few they can spare at a reasonable price. I heard they range from $20~$30 each, and I have a 66G, so looking for at least a couple or more.

I have tried seagrass filefish, but it couldn't take care of the roots, now they are coming back and I lost half of my corals to the fish...

Tank is being infested with aptasia right now, biggest one is about a quarter when fully opened, and beginning last month, small tiny ones are appearing everywhere, where I can see (reach and non-reachable), easily over 15, 20 (assorted sizes) aptasias...

Thanks!
