They get very, very big too. Another thing to remember.

Yeah, got my juvenille niger in a 46 g, then in a year or so we'll upgrade for sure!

I was planning on buying a juvenile and he would go into my 190g. He would be fine in there. If he did get to big I would have to part with him (or get a bigger tank :)).

Thanks for all the replies

Probably would be fine for a long time in your 190G...they grow very slow. My brothers has reached about 16" now and is very active so needs a lot of space. I think its taken about 5 years though to hit the 16" mark.

I had a male blue throat in my reef tank he was very docile towards everything and much nicer then a niger. But Get a male the female are kinda bland
