Small Bottom Feeding Fish

[Ruskull]

Can I recommend Trilineatus (False Julii, Three Lined or Three Striped) Corries?  They only get around 2 inches long and to be honest I've kept them for a couple years & they aren't any bigger than an 1.5 inches at the largest I have.  You could easily add 6 or 8 in a tank that size.  They help clean the bottom a bit too.
 
As for your substrate:
I've kept Corries in my 36 gallon which is a mixture of black sand & black gravel & they did fine.  That black gravel is very rounded keep in mind,  Now I keep them in a 20 gallon and they seem a bit happier with the Quickrete playsand, which is a finer sand that has a bit of sparkly quartz to it.

Yeah im going to get some more sand to put ontop soon and im trying to get most of the gravel out so its mostly sand. Only thing is my petco doesnt have many cory species so i have to order them. The only cories they have are albinos, emeralds, and peppered.

My Petco has Julii Corries, which are really Trilineatus, so does Petsmart and they label them incorrectly as well.

They have "julii" cory cats but when they get their shipment of them in, its usually 2-3 of them and they all look sick so i wanna stay away from them if every week they come in sick. I wish my petco had a special section of tanks where they order in not too common fish instead of having the same types of fish every month.
