My tank has been up and running for about 2 months, and things are going well. One fish that I'd love to get in the future is a Mandarin Dragonet (or Goby). The colors are amazing. Now I've read they should only be introduced into a mature tank (ie. 6 months) since they feed on live copepods. I'm assuming the copepods take a while to develop in a tank?? If I were to buy a "bag o' copepods" and add them to the tank, does it cut down the time?? Is there a risk involved in doing it this way.

Mandarins are gorgeous but should be kept by experienced reefers with large tanks as they GENERALLY perish from lack of food source. I capped generally to cut out all the fighters that will now join online for the great mandarin debates. It is possible from time to time to experience a mandarin that will eat frozen cyclops or rotifers. That is not at all the norm. It is also tedious to feed them like that. If there are other potentially faster fish in the tank the mandarin will generally be shy of those fish and skulk in the back waiting for a bit of food to nibble. Adding live copepods or allowing them to thrive in your 29 (what I saw in your profile) won't help much at all since the mandarin will quickly strip such a small tank of any. It is a good practice to keep them in a tank no smaller than 75g. Not to discourage you in any way from keeping one, just understand the patience and dedication it may take in such a small tank.

Thanks for the information. I'd much rather know the pitpalls up front. Discouraging would be scooping one off the bottom after having it for 2 weeks. I'll just wait until I get a bigger tank.

Thanks again.
