Some strange grey-ish green tentacle like stuff is growing from the lip of my air tube and on the nearby plastic plant that touches it. Algae also seems like it has made itself comfortable on the air tube and the coliseum decoration. Is it safe to leave it be or is there something I should do about it? I've never had this problem before, but this is the first time I've tried my hand at having live plants in the tank.
I would take a picture of it but my camera has decided to die and refuses to charge.
I have a 9 gallon biube, 3 tiger shrimp, two cherries, three ghosts, 5 neon tetras, 5 danios, one oto, live elodea. Halogen light.
No fish have died, all shrimp are accounted for. No strange behavior from any of the fish, they're all eating healthy.
