All right I have 2 rbta's to share. These split fast on their own, are very hardy, and have survived a 2 crashes in my tank. In fact all my rbta's seems to do just fine no matter what happens in my tank >< You can choose from the roaming 4. Heres the rules: 1.) You must have very high wattage t5's (54 watts+) or at least 175's mh on your tank. Prefer a combo of both. 2.) You have to SPOT feed them once a week with some sort of brine/mysis/rotifers. And once a week with soaked flakes (it works trust me). 3.) The first two splits must be given back to the chain before you can sell any more splits. Know how and when to propagate them . 4.) Tank must be running at least a year. Don't kill them with new water. 5.) Tell us what color hair your first crush had, if you can remember. I will add a picture tomorrow.
