I am planing my 30 gal tank is a newt completly aquatic? i would like critters and fish Is that even possiable

newts need some land or floating plants so that they can get some air. they are not completely aquatic.

They make floating logs and decor for critters in your situation. You would just need to keep the water level a couple inches lower than normal.

newts need land, they should have 50% land, 50% water

I find newts crawling on trails in forests alot, so no, they are not fully aquatic. Leave atleast some space for them to crawl on when they are not submerged.
I would suggest adding a rock that is flat on the top, or leaving a small island in the tank
Also, you might need to upgrade to a bigger tank size. Newts need alot of space. i think a 40g breeder would work if you ever got around to upgrading.
I am sure you will have alot of fun if you get newts. I was once at a lake where they were spawning all around me, lol. I got to watch them swim from above.

Paddletail newts only come out when there is something wrong, so they are fully aquatic. There are others, but that is the only common one I know of. They will go for fish though, so they would have to be either too big or too fast to be eaten by the paddletails. The other option is to just add a lot of feeder guppies and let them keep replacing their losses.

Even setups that are not fully aquatic can have fish in them. My 55 is setup as a viquarium so it is about 2/3 water that is about 6" deep and I have tons of guppies in there, and could have put in many other types of fish, not just guppies.
