And where are you going to take the hybrids every month? You realize you can be over-run with fry in about 2 months? 10 gallons will hold about...5-10 full grown ones. Most batches have more then that.
Anyway, now it's up to you. I urge you to totally think this through, have true homes planned out for them, and know what you're getting into. I suggest you read through all the posts again, and take into account what everyone is saying, without thinking it's a attack on you, as some have some very good information. Then make your decision. Good luck with whatever you do.
