My wife has a ten gallon tank with two amazon sword plants (one floating and one in a pot), some java moss, and a few odds-n-ends decorations.
Lighting is the flourescent strip light that came with it. The tube has been changed a couple of times.
The sword plants currently have a lint like algae on them which is also covering the odds-n-ends and the wire for the submersed heater.
This tank has had a moderate amount of various types of algae for years, neither seeming to take over everything nor going away.
Water changes are "infrequent" to "frequent".
Her panda cories have little panda cories occassionally so the little ones have to be removed and put in my 20 gallon tank.
Her population seems to run 10 to 30.
We are happy with this as long as the pandas are happy with this, and it seems stable.
Now.... as for the 20 gallon tank...
Lighting is one 20 watt "cool white" flourescent and two 17 watt "all glass" flourescents.
Two amazon sword plants (both 'floating'), water lettuce, anacharis, java moss and a slight case of green water.
Fish include one black molly, 4 brilliant rasboras, 1 tiger barb, 5 black skirt tetras (?), 2 kuhli loaches, and 12 to 14 panda cories.
The java moss is heavily interlaced with an algae that looks like someone pulled a cotton ball apart. When removed from the tank, it feels like "felt" fabric.
We would like the pandas to be happy and settled enough, etc. to breed in the 20 gallon tank as well.
Is the algae in the java moss preventing this or is there something we need to correct?
Any other suggestions would also be welcome.
