Is this staghorn algae?

[jeffteo]

I have been wondering for sometime if this is staghorn algae or some other. I can't seems to get rid of it using excel. It grow light in colour and will turn black slowly. Only way is block out its light source to stop it from growing.

No. This one in the pic have not apply excel yet. Don't think is BBA as it branch out when it grows longer and don't look like a brush as it is not thick.

Oh. My bba dark green turn white when I added excel.
You mention turn back to black. If you say confirm not then could be others. Staghorn grow quite fast but never see it fluffy looking like yours.

What i mean is when it first grows out, it is white and will slowly grow darker. Last time tried excel and not much effect.

Another one is growing.


It only seems to grow on the wood..

quite likely your guess of staghorn is correct... tried nuking the zone affected with hydrogen peroxide?

Might just let it grow into a staghorn algae tree. Wahaha...

Not staghorn algae...doesn't look like this. Staghorn algae is not so longish and is a greyish translucent branchy growth that does not change color much.

Sorry to necro, but I also have this growing on my driftwood and it doesn't look like BBA or Staghorn algae so I did a search over many many days and finally found this site http://www.planetainvertebrados.com....gos_ver&id=144 (In Portuguese)

Xylaria (?) sp. Hill ex Schrank (1789)



There are several reports of the emergence of structures in submerged trunks and branches in ornamental aquariums in Brazil. What motivated the elaboration of this article are these bodies. They are branched formations with a blackened base and white ends, with some variation in form, sometimes squat and thick, with a flatter end, other times longer and with the appearance of ribbons. Its appearance is very reminiscent of the terrestrial fungus Xylaria , a cosmopolitan genus with more than 100 species, with several species found in Brazil.


It is a terrestrial saprophytic Ascomycota fungus that grows precisely on decayed wood (the genus name comes from the Greek xýlon , wood). In particular, the appearance of fungi in aquariums is quite similar to the most common species, Xylaria hypoxylon, which is also the type species of the genus (called "stag's horn" or "candle-snuff fungus") . It is a terrestrial fungus, but interestingly the records in New Zealand are quite atypical. There, this species was most commonly found growing on submerged trunks decorated in running water.

Mine looks exactly like OP's second photo with white top branches and black bottom half. Very interesting so don't have to stress about it being BBA or Staghorn algae
