Injured molly

[JulijaLu97]

Hello, I have noticed this morning that one of my Mollies is injured or got an infection, not sure?? Is there any way I can help him ? And do you know what it could be ?

What else is in the tank? can we have a water parameters?

looks like an injury.

do a 75% water change and gravel clean the substrate.
make sure any new water is free of chlorine/ chloramine before it's added to the tank.

add 2 heaped tablespoons of rock salt, sea salt, or swimming pool salt for every 20 litres of water. Keep the salt in the water for 2 weeks.

Ouch! Colin is our expert here so follow his advice. Is there anything sharp or pokey that it could have hurt itself on?

Besides the injury which @Colin_T has addressed. What other types of fish do you have with him ? Also like @JuiceBox52 pointed out did you check for sharp objects? Possibly the edges of the sea shells.
