Could it be the blue green algae - cyanobacteria?

 

[fishyjessie]

What is this cyanobacteria? Is it good?

I don't know if it can do any harm to adult fish but u have to be careful if u have frys. This kind of "algae" (it's actually bacteria) will blanket the aquarium and if there r frys resting on the substrate etc, the "algae" wil start to grow on them leading to suffocation.

It's linked with high nitrate and phosphate probably caused by overfeeding, overcrowding or poor water quality so u may want to do a more frequent water change, and reduce the amount u r feeding ur fish. HTH!
