Hello guys, wanna ask is a 10 litre tank suitable for fish ? Recently gotten 6 mollies… 3 died after a few days and I start researching more on the parameters..

I’m using hang on filter, there’s two fake plant deco and a small wood with tunnel to hide that I gotten from the aquarium store.
Using tensiongon, bactoclean and JBL pH Plus. Feed the fish once every two days.

One of the molly had 16 fries, quarantined them in a self make container with holes suspending above, now left 1 🥲 fed them 3-4 times a day. Will clean the remaining food.

Tried getting ammonia and the other parameters in control, things seem stable for a week or two… then the other 2 molly start swimming less and just staying on the bottom, eventually they passsed on two days ago 🥲

Not sure is it cz of the male molly keep chasing after those 2 or not..
