Noice zip zip from my nano tank

[michaelmah]

I realise some insert noice like "cangkerit", I switch off all my electric item and take out all my plant and shrimp to another and just left gravel there.

I though have some Perator insect gone into the tank and attact my shrimp.

I still hear zit....zit ....zit... when i put my ear to glass of tank.

But at the end found nothing.

I suspect the microganisma/ incert making such noice.

Do you all encounter this?

You all try switch all and put your ear to tank. I dont think the shrimp know how to make noice. Plant? then what else create this noice?

Might be the dragonfly nymph?

but I confirm when take out all thing included plant and shrimplet also cant see anything on the gravel.

After that I did some aquasraping also.

I suspect my CO2 diffuser causing this.

look in your soil / gravel. It might be MTS Snails.

I think it is the CO2 diffuser. Mine makes this noise too.

mts snails will cause that noise?

my nano cube doesnot have the mts snails.

I have 2 apple snail, but they dont make noise
