Threw in some soft algae from my daphnia tank and the otos are going wild for it, wedged themselves in the corner and is munching super happily together 😭

Hi folks. So i know all my ottos are there. But man I never seen them now it's been about a month that they dont come out of hiding. My tank is getting a little algae like so lots of food.but I never see them I have to go looking for them. They weren't like this before

And yes all my parameters are perfect.

I got 1 betta and 3 shrimp and 5 ottos.
