What is it?

Should be soon! Once 4 legs are formed the metamorphosis is not far away. If you are have not done so; now is a good time to prepare a ramp like access to dry area in tank. Can be done by creating a dam; using a turtle dock; or having a mass of plants frog can climb into.

Rana's do well when in mixed water and dry enclosures. This care sheet should work for them even if written for the Leopard Frog: Frog Forum - Leopard Frog Care - Rana pipiens (Schreber, 1782) and R. sphenocephala (1886). Myself prefer a ratio of 75-60 water and the rest dry; but most keepers do 50-50.

Species final size will determine aquarium size. If a Bullfrog; you might want to consider grabbing a 55G before the $1 a gallon sale at Petco ends later this month. A mature Bullfrog will use all that tank and if a larger female, will eventually need a larger one .

Looking back at pic no. 3; does looks like Rana clamitans !

sorry with all the questions but he also likes to stick himself between the filter and the aquaruim wall . any idea what he is doing?

[Sothfo]

also sorry with the comments but i have found an heat lamp in my house and it just takes any bulb so would it be safe for an frog or is it too hot?And i added some eco earth

There is no telling on why frog is hanging around filter; is the outflow strong?

I don't think your frog will need a heat lamp if tank is in the average room temperature. Still, you can use that dome reflector with a compact fluorescent or LED bulb that provides visible light spectrum to illuminate tank and grow live plants if you have them .
