have a 20 gal in the works. i'm planning on having a school of 6 or 8 tiger barbs, 3 or 4 yoyo loaches (hopefully the lfs that has them now will continue to stock them), or 3 or 4 botia striata (if i can find them). was kind of going for the whole species tank thing and was going to leave it at that. but is there any other fish that might work with this school of tigers (other than bottom dwellers) or should i just stick with the tiger barbs and call it good?
