What substrate should I use?

[douglas]

Greetings from Singapore! I am new here.

I am deciding what to use as substrate.
Any suggestion? gravels? sand? none?

BTW, would it be safe if I use a algae eater...which does not have spiky fins?
I am aware that spiky ones would hurt newt if consumed.

Hi Douglas,
In general I personally do not use any substrate on the bottom of the tank although other people use sand or gravel that is too large for the newts to ingest.

Hi Ed,

Currently I am not using any for them. Just wondering if I should....

BTW, regarding the algae eater fish.... it was gone, I think it became food....
