2.5 unfiltered work tank - which invertebrates?
So, I've got MTS. *chuckle* What can I say.. my LFS had a sale. :3
I recently purchased a 2.5 gallon tank (my second for work - the other one's in reception, not at my desk), put in some substrate from two established tanks (white sand and Eco-complete, resulting in that salt & pepper look) and planted a bunch of stuff in it.
2.5 gallons (12x6x8) All Glass Aquarium
No filter, aeration, or internal gear
Shares a Home Depot desk lamp (you know, the one that's popular on so many little tanks) with a small potted croton - light intensity is easy to change, duration 9 hours (one work shift)
7x C. wendtii green (seriously.. one pot, seven healthy crowns and a couple babies I didn't count. They're all little for now, but I fully expect to move them as they mature.)
2x Lobelia cardinalis, also little (3" or so, which I also expect to move as they mature, or maybe coax into growing emersed? Google seems to think these cute little fellas will mature into monsters.)
One pot H. callichtroides
I have access to a bunch of other plant species, so if a fast-growing stem or something is needed to suck up nitrates, I can get it.
Water changes will be weekly or more as needed; the water will go to the many potted plants on the desk, so that won't be an issue. The local water conditions out of the tap are:
GH and KH off the scale - VERY hard, perfect for invertebrates
The substrate from my other tanks brought the standard complement of snails: Physa, Planorbidae,and Melanoides,which I think are rather cute and won't be getting rid of. Right now there seem to be two or three of each. I fully expect them to breed like bunnies.
What I'm wanting to know is this:
What kinds of critter can I add without adding a power filter? The power outlet at my desk is full, and I would get in trouble for bringing in my own splitter.
I'm thinking a handful of some color of Neocaridina, or a single/pair Amano shrimp, or maybe even an apple snail. Thoughts?
