Shark questions

[Paige2]

Hi guys,
I am looking at getting a 20-30 gallon tank and I was going to put 2 ID sharks in it untill I found out they can get really big. (I was told they only grew 4-5 inches). What other kind of shark could I put in my tank that doesn't grow as big?

You could put one red tail black shark in there, they get about 4-6 inches. Look on the profile section and it tells a little about them.

I've had a redtail shark in the past and it caught something and we checked all the lvs of the tank but he died shortly =/
The kind of shark im looking for are the ones that look more of a shark such as the Id shark. I've also had a rainbow shark which is in the tank we have right now. The id shark seems the only way to go right now but I couldn't house one that gets as big as it does.
