Opinion on tiger barbs

[Corypower]

What other fish are in this tank. I'm just wondering why all the fish in the first photo are looking down and backed up into the plants.

Just a sword tail , do read all the post

Beg my pardon, this just seems to be unusual behavior.

No it’s pretty normal for any fish in a planted tank ,that’s what plants are for

Some overhead shelter (floating plants) and a dark backing on the tank would help the fish feel less exposed.

I was told tiger barbs need a open tank

Plants floating on the surface won't cut down the swimming space. They make the fish feel more secure - they don't know there are no birds etc about to eat them - and they diffuse the light.

I don’t have a light

I am curious. How well do your plants grow without a light?

Natural light it’s near a window,you might think algae is a issue but it’s really not

The window light without an overhead light is likely working here because the plants are Java Ferns which are low light/nutrient requiring due to their slow growthy habit. No tank light does however make observing the fish and aquarium more difficult, at least it did for me when I tried this for a year with one small tank. And algae was more difficult due to varying intensity and duration of natural light. I moved the tank after a year (it was an intentional experiment), replaced the overhead light, and I was more satisfied with this.

If I add a light now the algae would just explode ,and it’s actually not that hard to see the fish

In Singapore is the number of daylight hours quite consistent across the seasons?
Also, in summer how hot does the tank get and for how long?

Hahaha we don’t have seasons here and ya it’s gets about 30 degrees,we get about 12 hours of sun

Got it.
So my worry now is that the water in front of the window is heating up way beyond the tiger barbs natural temperature maximum of 26°, for most of the year? Or do you have air con/ chillers?
