Air stone/spray bar needed?

[wnorman293]

Hi all, still quite new to owning newts. Got a pair of juvenile Spanish ribbed newts in a live planted tank. Got a sponge filter running near the rear left corner, but after reading up on water oxygenation - Was worried the other end of the tank wasn't getting enough surface agitation?

They come up for air now and then, so I'm guessing that's normal for them and they don't like strong currents I've been advised. Here's a pic of the setup at the moment. Do I need anything extra?

Hi,
This setup looks fine.
Perhaps some more live plants (much plants improve water quaity, but also allow ribbed newts to sleep vertically, nostrils out of the water).
The land area is not useful for this species.
Be sure the rocks are stable and cannot fall on a newt : ribbed newts are a little fossorial.
