As the subject says, what would you put in a 5.5 gallon tank.
I'm thinking of putting one that size in at my desk at work. I think it would be small enough to easily manage while not getting out of hand. After all, I'd have to use a bathroom sink for water changes and can't fill buckets. I think I could get a 1 gallon water jug filled though.
The first thought was a Betta ... but I'm not overly fond of them, they are just 'okay'.
But I'm not sure what else. I think a 5.5g is even too small for neon tetras. The length of the tank is 16 inches.
Puffer fish I think have been suggested before, but I'm not interested in them.
Snails only would be a bit too boring.
For filter, should I find an internal or use a sponge filter? I'm wondering if the bubbles from a sponge filter would be too loud, this will be in a cubical farm. It comes with a HOB, but not sure how well that would work.
