For my 75g:
I want live plants, maybe a couple big rocks, and unsure about how much drift wood. For fish id like a school of neon tetras, a few kuhli loaches or dojos and a betta, other than those i cant really think of any that really caught my eye.
Just how bad is sunlight? the place im thinkinh about setting up the tank is near a smaller high up window and im pretty sure the light it will get is mostly reflected since theres a bush blocking like 90% of a direct path from the sun. But that light will maybe hit like half of the right half of the tank.
Hang on filter, undergravel, or submerged filter? Since you said that too much surface movement wouldnt be good for the co2 plants and i know how much bettas hate currents. I do like the idea of 2 submerged filter on each side of the tank, i feel like it would filter it better, like having 2 heaters on each side.
What is best for substrate, gravel or sand? Ive always had gravel but i do like how in those show tanks they had made the sand to look like a river, i just feel like sand would get kicked up during water changes.
Driftwood. Im guessing it would be best to buy them but would it be a bad to go find my own and "skin" it and boil and soak it and all that on my own. Some of the plastic or whatever wood looking things are nice from pet stores but i like the idea of having a unique one.
Since it may get hit by a little sunlight should i get a pleco or a couple? And are there kinds that stay smaller because the black ones get kinda big and honestly, i have a fear of big fish.
Would it be good or bad to have most or all the ground covered by moss or some kind of tiny plants? I saw some that looked like mini clovers.
Any answers and advice is greatly appreciated.
