Custard Coloured Algae?

[connor_09]

Hi all, just a quick question really, I've recently discovered a custard coloured algae or growth on the silicone in the corner of my tank, any ideas what this may be? Any help much appreciated!

That's probably a bacterial biofilm or a fungus. All these things are common and nearly always harmless, going away on their own - I'm assuming this is a new tank. WD

Is it custard?

On a serious not i agree with waterdrop. bacterial or fungal growth, just wipe it away if it bothers you.
