This one can be a real tank buster. In my 10 gallon DIY c02 40 watts compact fluorescent lighting, it is growing like crazy and I have to trim it weekly. The same for my 40 gallon with 2 55 watt AH supply bright kit lights and 30 ppm pressurized c02. Lol, it is almost as bad as duckweed.
[I]Puntius denisonii[/I] (torpedo barbs, roseline sharks) will eat the leaves of this plant. They will completely strip the leaves off over time, and keep eating any new leaves that try to grow.
I could not get this plant to do well in the tank with my [I]Puntius denisonii[/I]. I eventually realized the fish were eating the leaves.
I have moved this plant to another tank that does not have any [I]Puntius denisonii[/I], and it has grown back very strong.
it was doing well in my aquarium during winter(i live in a tropical area where temp drops rarely below 12 deg C in winter) but as summer came in and the temp soared in the 40s,it grew thinner and now it is looking like a mass of few entangled threads with small leaves about 2mm size.
