Delta Guppy not moving

[sammiimaac]

-10G tank, 78 degrees F
-1 male Betta, 3 male tequila sunrise delta guppies, 3 male silver tip tetras
-50% water change done on the 13th due to clouding water, added tbsp salt
-KH 80 ppm
-GH 120 ppm
-pH 7.0
-Nitrate 20 ppm
-Nitrite 0 ppm
-Ammonia 0

One of the sunrise delta guppy’s seems very unhappy... looks “bloated” compared to the other two and is just hanging out at the bottom in the corner. Thoughts??? A little worried about the tiny guy.

I haven't kept livebearers in many years, but I think large frequent water changes can only help. Are you really sure it's a male? I can't tell.

A little bit of Epsom salt might help with the bloating. It's sold in the "foot care" area at big box & drug stores.

How much, what & how often do you feed the tank?

How is he doing now? Is he lying on the bottom all the time?
Are his scales standing out like a pinecone?
