Hair algae - siamese algae eater, nerite snails, amano shrimps, cherry shrimps, crystal red shrimps, ghost shrimps, feeder shrimps (at my place or in my country this will be thailand ghost shrimps).They do jump- I lost one too. Two left that argue alot. Grow like weeds mine are 4in long I guess on their way to 6in.
BTW what eats hair algae- that is what I was sold them for.
I read the silver flying fox eat dwarf shrimps.
