Recently purchased 2 BTA's. One rose and one green. Did a 2 hour drip acclimation. The green was roaming all over the container making me worry about the rose. After placing them in the tank they both disappeared into the rock. Two days later the rose was out, open and looking good. The green finally emerged after two weeks. No longer green or opening fully. Now that the green is out will it regain its color? Is there anything I can do? I have been feeding them but not sure if the green is eating due to its location. Water parameters are good.
