T~C, you will be WAY ahead of your game if you give up on this 7 gallon tank idea, it's just not very reasonable. Do you realize that if you actually do get anything to spawn you will have 10 times the volume of your "broodstock tank" just in food cultures and larval tanks??? Your'e going to end up with a half dozen tanks at least, why cram the breeders into the smallest and most difficult one? ( must be a friend of Matts :lol: )
