I'm planning on setting up a 20 gallon High (24x16x12) with a high o2, planted, brook/river type biotope. Heres my current stocking plan: 6 Dwarf Neon Rainbow 3 Borneo Sucker Loach 1 Sumo Loach 1 Bamboo Shrimp 1 or 2 Sulawesi Rabbit Snail How does this sound? I've always wanted to try sumo loach but have heard they can be micropredators, how would one be with the inverts in a community tank like this? Also I have heard having too many sumo loach can cause aggression without adequate territory/hiding spaces, but will a single 1 do ok by itself? Any suggestions or thoughts are welcome :)

Are you guys set to release the Eques Pencilfish on Sunday or Monday? Just asking as I have a bit of a drive to get to the store and I want to try to get some.
