Ok i guess i'll pipe in here. I presently have my group of Dicrossus Filamentosus in a 20 long with my trio of Sp Mamore Reds. The Mamores are spawning and raising fry in the tank with no ill effects to my checkerboards. Now my Dicrossus havent spawned in there yet, but they co exist just fine. I do find my Mamores to be more aggressive then any of my aggies get. Maybe im just lucky!!
