Thank you for the link for black worms. My 28-gallon has completed it's cycle, with zero ammonia and nitrite. My 10-gallon has zero ammonia, and nitrite took a nosedive from probably 5 ppm to 2 ppm in a day and the next day was .25 and it has held steady for the past few days. I did clean off some brown algae off a few leaves of some plants and off a bit in the back, not sure if that is that is the cause it is still not zero? I am down to one dwarf frog and not sure if I will get more (guess which one ... I have named "her" Spice). My clawed frogs are still alive, but one isn't as eager to eat in the last few days as usual. I have been hand feeding them the reptomin pellets for several days now. The one ate two pellets and didn't want any more, and even spit some out. The other one stuffs itself as usual ... this frog actually comes up to my hand and searches around my hand for food.
