Yikes! I was going to add a couple of nirites to my 13 gallon w/bdbs after we break it in cycling to control brown algae and watnots. I heard they don't like sand either but was hoping they'd crawl on bdbs. lol
I hope the nirites I get aren't so picky of the substrate
Started out, thinking it's a 5gal. tank chore for my grandkid want, now, it's turned into a expensive hobby that I've got only myself to blame fer.
