everyone should relax on tank size suggestions lol
for life, of course huge is better. but this is reality.
i've had my tsn from 2" for 2 years now and he's only 20 inches or close to it. they grow slower then rtc, and even my rtc everyone said he'd be huge by now.
2 years, 2 of the biggest growing cats, and they are enjoying life in my 400gal and still look like babies. im sure i have, like 10-20 more years in this size tank til they "need" to be moved. even my 3 aros pushing 4 years old have plenty of room to grow in the same tank
