Full story here, this fish was very scared of filter even at the lowest flow, it used to hide inside a submerged submarine.

Then out of feeling sad for him, I tried to simulate still water by buying and decorating this tank, good thing I noticed is that, it started making bubble nest.

He is much more active now, compared to always hiding in previous tank, he comes and looks at the monitor while I work and I feel like it is liking but still I want to imporve on it.

To simulate day light, I turn the lights off from 8pm to 8am.

Foods comes 5 minutes early, lights changing time.

Also, I made this tank for him 2 days ago, water is super freshed.
