I have really enjoyed reading this thread, lovely tanks everybody!
OFL, forgive all the questions but I'm new to fishkeeping and NPT's really interest me as I love plants and always wanted to learn more about aquatic species. I have one betta currently in a 2g unfiltered (lots of water changes) and am very soon moving him to a 5 gallon.
-- Is 5g too small a tank to support this system?
-- If not, what kind of lighting requirements would a tank that size have?
-- Is store bought potting mix + clay litter okay?
-- What proportions do you mix those in?
-- Have you ever had any issues with disease from potting mix?
-- How deep does the soil level need to be, minimum?
-- Is fine aquarium gravel sufficient to keep the soil in place or is sand a necessity? Can gravel go over the sand?
-- If something's going to go horribly wrong, what's that most likely to be?
Again, sorry for all the questions! I'll look through some more threads for tips here, too.
