I was looking for Bergia Nudibranchs to naturally balance out my Aiptasia. Want to pick up around 8 breeding size adults. Figured I would check forum before ordering online. New to the MR, went to frag swap on Sunday & joined the very next day.
I first noticed the bergia on a piece of live rock I bought 6 months back. It was only one very small one back then. I nurtured it (direct feeding) until it became very large. When I identified it (1 week into me having it) I didn?t bother getting rid of it because I thought it was kind of cool (If only I knew). Then it started to sting my yellow mushroom. I promptly ripped it out of my tank only to find several more a few days later. I then destroyed those & sucked out remains. This lead to a larger outbreak. Lastly I tried a Kalk mix which seemed to work?. but you know what happened next. Not only did they spread but also it seemed to affect some of my polyps. I haven?t touched them & they haven?t multiplied since, but they have grown very large. I think they are growing by eating my very large invertebrate running all over the tank. What I wanted to do is breed half the bergia in a separate tank & put the other 4 in my display tank. Any feedback on how you gave them their best chance of survival would be great
