Cheers pal it's one of my favourite tanks atm.
Have a couple of fish to move out then I might consider some nano schooling fish, any suggestions?
Hyphessobrycon flammeus the flame tetra,bloodfin tetras,and thoracochorax hatchet fish are just some that can be found in the wild with borelli in the lower rio parana Argentina.Seems maginatus would be the only one small enough and I bet they arnt easy to find hmmm.
