Tiger barb looks a bit fat..

[sanasana]

One of my red wags became fat almost overnight. I didn't notice it growing fat at least, and I try to observe any changes in them as best as I can. I observed my tiger barb and it's a bit fatter than before too. Is it just me being paranoid or is it something more? Is it overfeeding? Though I don't think this one eats too much.

(I got two tiger barbs. I can't really tell their genders very well, though.)

This photo is about two weeks old.

I took these today.

Are the fish swimming around normally, eating normally and breathing normally?
If yes, then don't worry.

Male tiger barbs get a red nose when they are in good condition, females don't have the red nose and get fatter due to eggs.

If the tank has been set up for a while and you have room, and depending on what else is in the tank, you should add more tiger barbs to the group. They are a schooling fish and need to be kept in groups of at least 6 but preferably 10 or more.

And if you have some plants in the tank it will make them feel more secure and they will show better colour.
