Aquariums: The two aquariums that I’m maintaining in my room

I'm having two aquariums of different attempts at biotopes although the plants aren't exactly 100% accurate.

The first one being mostly South American with dozens of Tetra and a single Ram Cichlid that has been running for almost a year while the other, newer one being Southeast Asian with Harlequin Rasboras and a betta. Both tanks have bladder snails and Neocaridina as the cleaning crew.
