28 l tanks look better to add
Definently comsider adding some green whether its fake or live plants. Will also help give a bit of balance to the tank and fill out the top half a bit.
I agree with aussie, even a few plastic plants would give it more natural character, and you wouldn't have to worry about specific lighting.
Thanks alot I look into a couple of plants
I am really surprised that nobody noticed the fish you have in there.
You said the tank was 28 liters? If you have that small of a tank, and there’s a bala shark in there, you have problems.
Bala Sharks get up to a foot long, or bigger, and will require a larger tank, minimum of 100 gallons, with larger being highly recommended. The black skirt tetras are fine.
They asked for aquascaping options, not stocking options. So didn't bother mentioning.
Eg. If they were discussing stocking options, then yeah, or water quality problems, then yeah again. But asking about scaping, has nothing to do with stocking a tank.
