I had over 20 stems of pennywort some over 20"+ high and it was GEORGOUS! Right now theres nothing left, just a stump.... In less than 3 hours it went from beautiful to DEAD.
He had a H. corymbosa that effectively disintegrated overnight too...apparently...
and how are the fish doing in this tank??
What size tank is this?
Thats the thing i dont think that they are dieing. No bodies. I just cant find them in the tank.i've had brazilian pennywort in my 29 gallon very low tech planted tank. No fert, no co2, very little light, and it still grew like a weed. I'd imagine it wasn't pennywort but something else? dying fish are never a good sign.
