Well heres the problem. I have a 150 gallon Plaster tub i have my 23 in S.A. Redtail Catsh in. The Tank has began to leak (slow but steady). I got a 180 gallon in my living room basically empty. My dad is afraid of him breaking though the glass. The cost for a new plastic tub is out of this world. I have a couple people that will sell me a 300 gallon tank but at a costly price. I will only have the red tail in the 180 gallon tank for a tops of 5 months. And I was looking for some feedback about the red tail catfish breaking the glass. Atm i cant afford another plastic tank and i deffiantly cant afford a 300 gallon.
