That's true.. I forgot to mention the shrimp dinner part. A nice live plant would help deter algae some as well, but would need to be pruned of any dead/dying leaves should those come along. There's also magnet cleaners but for a 2g, they'd probably be a waste of money.sirdarksol said:I've seen elsewhere in the forum that bettas see shrimp as supper. In a tank that size, I don't think a shrimp would be able to hide from the betta for long.
I'm with FLBettaCouple, best bet would be cleaning the tank (and providing interruptions in the light source in the middle of the day to disturb the algae's growth cycle.)
