Newbie here but use to have aquarium years ago

Hi I just joined the forum. I am starting a new aquarium. 37 gallons. Will be putting live plants in it. I have a big piece of driftwood and rocks that I purchased from the fish store. I purchased 3 black Tetra and 3 Serpae Tetra. Planning on putting a Red Tail Shark in with them.

I had a aquarium years ago and pretty exciting to get back into it.
