I have a 29 gallon with a breeding pair of convicts. I have java moss and java ferns in there and they seem to be doing alright in the sand substrate without o2 or ferts. My ferns started growing plantlets so i picked some off and put them in a clay pot with some sand but a few minutes later the convicts dug them up. So I decided to put one of those breeder tanks in my tank and put the plantlets in there along with some sand and a few convict fry. The breeder tank is at water level so they'll be getting more light but will they still grow? Thanks in advance
