Fishless Tank Questions

[Willow]

i feed my lps regularly, they seem to eagerly take food so i imagine it is required for long term growth. last month i picked up a frogspawn colony from someone that had let the tank slide a bit over the years. i started feeding it 3 times a week. a week or so ago i noticed it has started 14 new babies on the underside. maybe it's a coincidence or just the change that helped im not sure but i believe that food is good for coral and necessary for some species.

even without food your lighting and water chemistry is still going to produce algae, along with possibly adding it on new stock or it growing out of your rock. i think you are always going to need some form of cleanup crew albeit a much smaller one without fish.
