29's are made as taller 20 gallon longs, while true 30's are 36" long. Unless it is custom built, it is not techincally a 30...just being picky I guess.
The brichardis will not use them though...they are substrate spawners, not shell dwellers.
Yeah i have shells in my 29gal Brichardi tank whale eye shells to be more precise but i do know they wont use them they only go in them to be nosey mine are more for the looks is all..
I still really haven't decided. I am supposed to check with the LFS Friday-ish on what is being/was ordered and when. It's a good thing that nothing was in because I was way too eager and would have ditched the two FM's before I could remove the fry. They just went on their first excursion through the tank a couple of hours ago. I will put them in my ten when they start venturing off on their own.
