As i often state, im no expert. I know a guy who has some large soribum, and theyr alot thicker than the elongatus than ive seen. I'm not saying that you should shove information peoples throat, and yes treat people, like you wanna be treated, is always a good idea

But, stilll that girl, either knew what she was selling, or she should have said she didnt know. Sometimes if i confuse people, its not because i mean too, but because of my bad english.
I dont think an Soribum Lima would outgrow an 75, atleast it would take some time. I've heard some people say it will get to large, others say it dont. TSN's are as you know beasts, and even tho theyr meny places listed as only needing an 180g............ you know all this

From what i've heard all the TSN's get to about the same size, without alot of difference, again im no expert.
Again, i think that girl at the fishstore, did wrong by either lying or telling someone, about something she knew nothing about, no matter what it would have had the same result... a fish that grows to 30", in a 55g..
