Hi. Something interesting that I have discovered - Lemon tetras eat brush algae.

I have a guppy tank outdoors which has got brush algae at the moment. Too much light and the CO2 ran out..... anyway, I've had no time to get siamese algae eaters to put in that tank to eat the brush algae. But seeing the brush algae bothered me so I moved the worst brush algae covered plants into another tank indoors which contains (amongst other fish), siamese algae eaters and lemon tetras. The idea was for the siamese algae eaters to clean the algae off the plants before putting the plants back in the guppy tank.

While I was looking at the plants, waiting for the siamese algae eaters to nibble at the algae, I noticed the lemon tetras were swimming by the plants and making flicking movements. When I looked closer, I realised that they were nipping off the brush algae, chewing it then coming back for more. They don't nibble like the siamese algae eaters but the nipping action doesn't cause any damage to the plants and the lemon tetras are faster to get going on the brush algae than the siamese algae eaters which are a little nervous.

Thought I would let you know.
