I'm looking for a small bottom dweller for my 6.6. Something that will stay on the bottom away from my female beta. Most corys and other bottom dwellers need a bigger tank from what I've been able to determine.
I have thought about shrimp, but they are still too food-like for me to consider as a pet.
maybe the pygmy cory but cories like to have companions so it's best to get 3 or 4 at least and that is quite a small tank for them. i think the best option is a couple amano shrimp. they get to 2" max and would help eat any algae or leftover food although they wouldnt stop an algae out break.
If you put off what you can do today until tomorrow it will never get done cause tomorrow never comes. It's always today.
