The molly fish are active and peaceful in a 10-gallon tank. I paired them with some tetras and they get along well. The 4 cm size is perfect for a small setup. Easy to feed with flakes and algae wafers.

I noticed the males were a bit territorial when first introduced, but after a week they settled. The fish are colorful and enjoy the surface activity. Good for a community tank with non-aggressive species.
James Newman –
They’ve been in my tank for two months and still show interest in food and exploration. The size is manageable, and they don’t stress other fish. A great choice for beginners.
