I have some kind of brown flatworm in my 75 gal. I noticed them condensing in areas with algae and/or copepods. I got a blue velvet nudibranch instead of trying flatworm exit. Here’s what I have learned:
1.) Run activated carbon. I use R0X .8 from BRS.
2.) Nudibranchs have no ability to tolerate moderate - high flow. I had to turn off my wave makers, angle my return pump upwards, and move some rock around to make him happy.
3.) When flow is low enough they are EXTREMELY active hunters.
4.) They eat by extending a proboscis looking apparatus and suck up their prey with surprising force.
If anyone on the west coast needs a blue velvet nudibranch, I will lend you one as long as you pay for shipping and have a plan for how to decrease your flow (particularly on the sand bed).
