How big is it now? This will happen quickly, especially a male. Water quality, temperature, and nutrition will all play into this. I would say measure in months not years.
mine finally took to prawns and tilapia fillets. so he should grow alot more now, then when all he would eat was flake food. now f he would just eat my NLS pellets.
Nice! That is great info. Mine is only about an inch and a half right now eating mostly bloodworm. I got it in the spring and it was tiny. It recently really started to grow. Here's hoping it grows quickly from here on out. Thanks to all that replied!
