So, i am going to get a betta sorority sometime soon, i have a cycling 29 gallon right now, but i need some good places for them to hide!
I bought a big 80 pound bag of concrete because it was just so damned cheap, and 10x more in there for 5x less the price of the little tubs, so, what i still need are Styrofoam blocks i may have to deal with walls though, and not blocks.
What i plan on making is a three tier corner decoration piece, on each tiers it will have a sort of "plant pot" for live plants, and behind the plants will be a cave for the fish (but if i use walls, not cubes, then it wont be a cave, but a door into a hollow room...
and after i build it, and smother it in concrete, i dont want to paint it, but instead cover it in the gravel i use for the tank, so it matches nicely.
my questions are:
will the plants do well in a small "pot"? i'm talking like, 3 inches each. the plants i think will be Anubius Plants.
How well will the gravel stick onto the cement? will they ever pop right out? should i mix the gravel in with the cement for the last layer of cement?
After letting the cement set for 24 hours, i will put it in the empty 29gallon, and do a waterchange while watching the PH levels, is there anything else i am missing here?
