I'm gonna be honest here. I love all fish but we have a problem in the hybrid world. I have 3 tanks in my house a 120, a 75 and a 50 salt. I have 10 year old plus hybrids in my freshwater. I have lately seen 1 to 5 yr old hybrid fish coming up with hole in the head and other diseases. I am now gonna e n d my hybrid endeavor. We need to work together to find what's wrong . This is all I have to say.
