I'm planning to get a mandarin goby and train it to take prepared foods in a separate 10g tank. Yes, I know they need hundreds of pods per day and I'm prepared to breed them. The prepared foods are to be a supplement to their diet. My question to those who have experience training them is should I get a small mandarin (no more than 1"long) or a larger one (over double that size)? The guy at the lfs suggested small because it has spent less time on the reef but I was wondering if anyone here would suggest differently? Thanks!
