You can always try a dottieback and maybe either a coral banded shrimp or, in extreme cases, an arrowhead crab (but, the arrowhead will really limit the rest of your cleanup crew choices).Yes, my tank is 29 gallons. My initial plan was to get a clown fish and wait a while for everything to stabilize and make sure the fish is healthy, then maybe add some bumblebee snails and eventually a small tang which I will trade in when it appears to outgrow the tank. My goal was to establish an algae eating fish into the tank before adding light. As I do not know anything about par levels or growing coal yet. And I want to avoid an algae outbreak.
The Bristol worms are my main concern making me think I should get some kind of parasite eating fish
The Dottie back and shrimp help with the juveniles, but not the mature worms. Bristle worms aren’t ‘bad’, they’re just unsightly.
As far as algae? Can’t beat an urchin and some Mexican turbo snails. They’ll outperform any fish option hands down.
