I didn't want to ever make him flare because I heard its stressful for them thinking some other male is in his territory, but I always wanted to see what he would look like if he did. So yesterday, I was just sitting there looking at him just swimming around doing nothing, and thought maybe he would like something to play with! so I got a small bead (not too small so he would choke on it) and dropped it in the tank. He swam up to it and pecked at it until it floated down. And I guess that startled him because he straightened his fins and flared his gills! I got my phone and shot some picks! You can see the bead in the pictures
I couldn't get THAT good of pictures because
1. My phone camera sucks
2. He kept swimming all over the place!
3. His dorsal fin (i think that's what its called) didn't exactly flare ALL the way in the pics I got
But theyre still okay. next time he flares, ill get better pictures!
