This 20 long is home to 9 green neon tetras, 5 otos, and 12 pygmy corys along with a hand full of neocarodina shrimp and ramshorn snails. But I see the shrimp more than anything else! The neons come out in small groups during feeding time but the rest of the time they all hide in the back together. Could it be possible that the flow is too strong? I have a wave maker on the right side but it flows down the middle of the tank. I would think if they were trying to get out of the flow they would hide on the left not the middle back.
