I don't know about the growth rate for some of those fish but if they all grow around the same rate, you're gonna be like one of those people that has a 55 full of big cichlids lol
Well i figured majority of the 7 bass would hit 12 within the year and slow down
The 5 widebars have grown about 1-1.5 inches in the last 8 months
Tinfoils and bichirs will prob slow down close to 12 inches
Gar and clown knife prob slow down after 12-15 inches as well
Fire eel growth rate will be slow since hes 14
The marbles wont grow much more
Silver arow, ripsaw catfish will prob get to 2 feet easy then slow down
These are just my guesses lol
