I'm helping my husband stock his 20g standard tank. The only for sure fish are 1 female Bolivian Ram and 1 female GBR. Platties and guppies are ok, but I have some in a different tank. He wants to do something that I don't have. I thought some cherry barbs would look nice or maybe a Honey or Dwarf Gourami. He wants it to be colorful. For the record, none of the stores around here have Endler's so that option is out. Corries are out because of the Rams (I don't feel there is a big enough footprint to add a happy school of corries). He'd like to have a Golden Wonder Killifish. Anyone have experience with these? Any other suggestions are welcome! Remember, the 2 rams are the only definites!
