Want a plec for my 240L and out of them all i think i like the sailfin plec the best but hear they grow to be the biggest..how long would it take for one to go from LFS size to say..7". and 10"? Months or years. I wont keep one in an unsuitable tank so once it grows i will either have a bigger tank or have him rehomed..but if i can put one in a 240 for at least a year then ill get one..
