Im planning a 29 gal
tank. How big of a clean up crew is too big? I understand that at a certain pt they will mot have enough to clean and as such will be supplemented, but is there a limit? I was thinking of a couple of skunk shrimp as well as peppermint, a fighting conch, astrea stars, astraea turbo snails, and maybe an electric blue hermit or a dwarf hermit. It'd be pretty cool to have a tuxedo urchin as well.
I think that's a lot which is why im asking, is there a cut off for your cuc if you're supplementing them?
