Hydrocotyle tripartita - more bushyMy filter is 2 sponges driven by an air pump that turns over 1 gallon per minute. The heater is set to 75F. I want a tallish plant 8 inches+ that would be happy sitting about an inch from the sponges and heater. I know that Egeria densa does well but I would like something a bit more interesting. It would need to be a low light/low tech plant, any suggestions?
