Hi I found a few aptasia in my tank don’t want them to get out of hand looking for a few Berghia nudibranch hopefully in the london area please let me know if you have a couple thanks
If it is just a few, berghia nudibranch are difficult to use to remove aptasia. They can be effective provided you purchase enough and have enough aptasia to sustain them long enough to get the population up to remove all of the aptasia. They work really well in a control situation where the tank is only the affected rock with no fish. Fish feed in the nudi's. Manual removal is a great option as well as a proper peppermint shrimp if you can find one.
I bought a peppermint shrimp on Friday hopefully it’s the right one I’ll give it a few days and see i haven’t seen her (was caring egg)since I put it in
