So I just looked at my tank shortly after the lights went out and I noticed that I have more digitate hydroids than I realized. To be fair I knew I had a few but they never caused any issue so I didn't worry about them too much. I've been feeding more frequently to keep my nitrates detectable and I suspect that has aided in their growth. It's still not an alarming amount but more than I'd care to have.
I've been reading online about them and all of the information I am seeing seems to be very mixed. From they're harmless and will eventually fade, to they will take over the tank and kill everything and eventually murder me while I sleep. A lot of the information I've been reading seems to mix up digitate hydroids and colonial hydroids making it even more frustrating to find reliable information. Does anyone know of a predator that will eat digitate hydroids? One place said foxfaces may but I think they were talking about colonial hydroids. Then somewhere else said Halloween hermits crabs would.
What would be your approach to kill off, or at least limit the population, of digitate hydroids, without using the chemical method? I don't have anywhere near enough to use chemicals.
