Bastardfish...He's looking good mate.
I was talking to my Thai friend today and he said the key to good RTs is patience.They go through many many stages and grow slowly so you need to just keep the water parameters good and give him good food.
Keep up the good work!
Forgot to add:
RT's are different to Flowerhorns in their growing process.FH's grow quickly and show their good points after a few months,RT's can take years.
