Low-tech potted plant questions
I just emptied out my tanks and moved cross country, so I'm working with an almost blank slate. Literally, actually; I have slate tiles that I used for the bottom of my goldfish tank and I'll be reusing those because they work well for goldfish. Anyway, this will still be a goldfish tank because I still have the fish. I was able to rehome my other, more herbivorous critters, though, so I think I can finally plant some stuff. The tank is too deep for me to work in much, though, so I'm thinking of just a few potted plants. Yeah, I know, not very natural looking, but neither are these fish.
I was considering using one or two terracotta planters, about 4" x 4" x 12" towards the back of the tank and putting something tall in them. Jungle val seems like it might work. What would be the best substrate to put in those pots? Would I be able to get away with low light (no, I don't know just how low--currently it'll have default factory lighting plus some natural sunlight)?
Any tips? Can I make this work without doing a lot of work?
