I'm looking for stocking suggestions. Here's my tank info. I follow the 1cm of fish per liter of water rule.
filter+heater (I bought my equipment used, so I don't know all the tech details)
23 Ember tetras (max size 2cm each)
7 Panda corydoras (max size 5cm each)
roughly 23,000,000 pond snails
The embers tend to hang out much lower in the tank than I expected, and with that plus the cories, pretty much all the action is on the bottom. It would just be nice to have something in the top portion. I've got roughly 15 cm left of "fish space" that I can add.
I'm not interested in overstocking, and I don't HAVE to have a new fish right now. I just think aesthetically it would be a little nicer. I absolutely love my ember tetras, and seeing them school a bit more thanks to a new fish in the tank would also be cool.
I really love the Pearl Gouramis (12 cm, just one obviously), but that fish is so huge next to my embers that it might look kind of weird and off balance.
Anyone have fish suggestions?
