Poor tank condotions. The P.H. in my tank went hay wire and I dont know why. I had them for 2 1/2 years the male in this pic was about 7" and the female about 5". They were bigger than the pic looks. A mated pair in a 55 is bad news, I guess we live and learn. They were shacked wp with a 5" Texas/Salvini Hy-bred, and a 4" neet. Rought tank.
