Kissing the tank???

[Jen21]

I just noticed my very preggo swordy rapidly kissing the tank (what looks like kissing). She keeps doing this and acting weird. Any opinions why

My platys love doing that!!

Its soo cool when they stretch there lips out isnt it? :heart

They are scraping the algae and other bits and pieces off the from the glass any other objects, and eating it. It's known as 'grazing' I belive.

It's a good sign!

Swordies will eat algea to some extent and they also will nibble on the plants! My juvies have really done a number on some of my plants so I had to move some of the new plant growth from the fry tank back to the main tank.
