I just introduced two new female bettas to my three females that I got a while back. They're all now coexisting in a 20H. The already established leader, Blue, faught it out with the bigger new girl who I named Ophelia, but now they're all fine and seem happy.
BUT I was watching them today and I saw the new ones nipping at a cheap plastic plant in the corner of my tank. It's a big rock with bamboo sticking out of it with plastic leaves. I looked closer at the leaves and noticed that they were almost all halfway gone from being nibbled! I never even thought that a betta would EAT a plastic plant.
I took the plant immediately out of the tank. Will they be okay? I don't know if they were swallowing it or merely ripping pieces off. Why would they eat a plastic plant? It wasnt like they were hunrgy. They did not eat the first night but they did the second one. They ate all of that plant in 2 days!
What's going on here, and will my bettas be okay?
