20g.......
 

is a 20 gallon long too small for 2 red ear sliders?

ive been throwing the idea back and forth..... doing 2/3 water and a 1/3 land until they grow some then build a plat form above the water incorporating 1/4 of the tank leaving 3/4 water.

anyone have thoughts on this?

Hm i would say its only big enough for one. These guys can get up to 12inches, so you would be better off sticking to one or getting a bigger tank for both...which would be better. Also a 20 gallon long is very narrow, they might get the the point where they cant even turn around in it.

You need 10 gallons of water per inch. RES get "the size of a dinner plate" according to www.anapsid.org. You're looking at a 200 gallon tank, or an indoor pond. Sorry. 20 gallons will work for a couple months, max.

I have One Eastern Painted Turtle about 5" long, in a 75 Gallon Tank with a bunch of Guppies (that he eats). He is 11 months old (my daughters caught him between his egg and the water). Started at 1" in a 10 gallon, then moved to a 20, then to the 75 because I could not keep the smaller tanks clean (and I finally ran across the 10 gal/inch rule). It takes every bit of flow from an eheim 2217 to keep it clean.

He'll be going back to his point of collection in June.

well damn, there goes that idea.... maybe ill get some form of lizard

Well if you wanted a turtle (mostly water) maybe you could just set up a vivarium for some creatures?

Firebellied Newts, perhaps. :D

Yeah ive heard their nice to watch! and ive seen some nice fb newts vivariums, and some cute pictures of the newts! i have a 20 gallon vivarium set up for 3 firebelly toads, but i wish the toads & newts could be housed together =( but theres some bad storys out there of the toads eating the newts limbs!
