As the title says I just got a pair of these interesting fish on friday and I have them in a 5g bucket until i can set up a 10g for them on sunday. These fish are F0's so they still aren't used to flake food yet.
Very interesting behaviors, I got worried today when I looked in the bucket as the female was just under the surface. I thought something was wrong with the water as I don't have a filter set up to circulate the water yet.
So I changed 65% of the water and came back an hour or so later. The female was still under the surface. I decided to feed them, they didn't eat the food but it looked like they were tasting it, sucking it in and spitting it out again.
Then I realized that the female must be "fishing" for little bugs that are coming though the broken screen. Never seen this behavior before but it all makes sense now

Just thought I'd share.
