I have my single young fantail, name is Blub, in a 10 gallon now, but his new 55 gallon is just about cycled! I like the look of algae, and Blub has taken a liking to it---however is there a possibility of him overeating? i feed him soaked hikari, peas, and occasional bloodworms from hikari. he's eaten today but is going nuts on the algae. little lines where he's nosed up and down! it's cute but i know goldfish dont seem to have a self-regulator when it comes to eating....should i curtail the algae or just let him go?
