Who has a frag only tank. I was thinking of adding a frag tank to my collection to help offset some ofthe expense of my main tank by selling a few frags, nothing extreme and not trying to make a serious profit, just something to play with and make a little on the side to help out with the main. Any thoughts on this or is it completely stupid. I was thinking about a 40 gallon breeder tank with a couple mh's and a few mj 1200''s
