Oh dear, I know the feeling! Rowena went nuts on the plastic on her gabber and I ended up moving her into a glass tank. I thought I could trust her in a mini duna now she's older and she's gone for the holes for the clips again
I stuck the clip back on and shes left it alone, but I used a nut and bolt of the gabber water hole and covered the clip holes with cardboard. Hope he improves, bless his heart, so glad you've taken him on x
