These fish are amazing!!!
My glass looks like it was cleaned w/ Windex from the inside, even the dark spots of algae!!!
Now, they're working on the driftwood & plants. I WISH they'd get around to the gravel (I was going to replace the gravel, but we'll see if it's not too rough). They cleaned the glass while the bettas (and I) were sleeping; the girls don't like their view obstructed by a little fish, so they butt them off.
I have a plastic net around the filter intake to keep it from jamming w/duckweed. It's covered w/ the brown algae. I was just going to replace the net, but now it will be food! I can put another net on the filter, & drop the old one in the aquarium for a snack. Hopefully, more algae will grow on the new net & I'll have food for the otos. They DO have a lot of plant cleaning to do.
Now I'm worried that I WON'T have algae. I'll have to start experimentingw/ algae wafers. Maybe there's one kind they like. I usually have frozen veggies, maybe I can concoct little, microwavable mixes for them. I'm thinking that it would be a good idea to start supplementing the otos w/ shredded, boiled carrot & spinach now.
