Looks fungal to me.

If you got black bush algae grow between your toes, you have a serious problem my friend!

@Vale! geez do we know what type of fungus and will it affect my fish / water?

Here are a couple of pics. I was wrong above, its not black, its white with some bits looking purply white . The segment of affected wood is about 7cm and its only in this bit







Rigt where the humbug snail is is where i am intending to amputate.

@Martinspuddle In the pic I saw upthread (maybe there are others that show differently) the stuff didn't appear to be photosynthesising: the portion behind the definitely-white bit in front looks greenish because of light reflected/refracted/whatever off or through the nearby plants' leaves?

Looking up the number for my chiropodist right now ...

... do we know what type of fungus and will it affect my fish / water?

I don't know what kind of fungus (if it is - see above!) but it's pretty common on relatively 'new' wood kept submerged and warm.

Harmless if there's not a lot of it and you just keep scraping it off every so often and removing it from the aquarium ; it'll disappear eventually. If there's an awful lot of it that's a different matter - in my experience it becomes populated with bacteria which, in turn, may deplete dissolved oxygen and upset the ecosystem in-tank.

...erm, think you might need to see the chiropodist as well @FishBubs.



I hadn't seen this picture @Vale! and yes your right that is not photosynthesising.

What started off as Black bush algae, has now turn into some sort of aquatic fungus. Normally quite harmless and when I've observed this on newly used wood, it's not as thick and usually disappears within a few weeks.

Sometimes, some species of Loricariidae catfishes will munch they way through it.

Its definitely not photosynthesising. Right, here is a scraping - its magic fluff

Popped it in a glass with a bit of tank water - it is white as we see it in the tank.



Took it out of the glass and put it on white kitchen roll - it is black

@Martinspuddle , @Vale! hi guys,
I am going to take the whole thing out because it is now spreading further than that small bit i had before and its bugging me. If treat it with H2O2 3%, do
1) i just rub it on with a cloth or does it need to be submerged in it
2) should i boil it after to be sure there is residue on it!
3) if i took it out the tank and left it out for a period of tine, would that kill anything off or will it just go dormant until its soaked again?

Has anyone used red moor wood in their aquarium ?

[fr499y]

Always used to use redmoor root.

Use a syringe and squirt it on the wood under water

[FishBubs]

Any reason why you no longer dont? Not being nosey, just want to sure its ok for my fish
