I've got a 4" Copperband in QT that is eating very well so I've been feeding heavily to bulk it up before it goes into my display, but don't want to overfeed. I can't seem to find a good answer here. I find "feed two or three times a day as much as they will eat in 30 seconds". I'd like to find a quantity though so I don't overfeed. I've been feeding it a couple dozen blackworms and about half to 3/4 of a frozen cube of mysis.
