I strongly recommend the Whisper filter. It is so easy to use -- you literally just take it out of the box and hang it over the side of the tank. No assembly required. Replacement filter cartridges (called Bio Bags) are sold separately.
depends on wat kind of turtle but normally a heat lamp a filter if u want a rock and something the turtle can hide under
I'm sorry but no turtle can live in a 2.5 gallon tank. You will need a least a 20 gallon tank and that is even iffy when they grow up I would say get a 30-40 gallon tank for one turtle.
A blue one
It's a snapping turtle. Come on, you should know this!
regular tap water
When they're a baby try a ten gallon tank. The tank will ned to get bigger as the turtle does so it has more space
Yes, every fish tank should have a filter, but depending on the kind of fish it can be exempt. If not an air bubbler is a good idea. The filter cleans the tank, along with putting oxygen in the water, and the air bubbler also puts necessary oxygen into the water.
You may be able to use a very small internal filter with a 2.5 gallon tank. You can check with your local fish/pet store and they may be able to show you ones that would work for your tank
A quality filter such as AC/Delco is the filter your should use.
