I have an RBTA that split last week the smaller half seems to have healed as it has moved all the way to the top of the tank to a smaller rock which I promptly put in tupperware and is currently zip tied/ hanging from the center brace of my tank. How long should I wait to sell it to get it out of my tank as I can imagine stuck in it's tupperware prison (with ventilation slits) it can't be as happy as it would be free to roam in someone elses tank.
