I have had a small RES for about 10 months now, I adopted him from a local lake I was fishing at. Currently I have him in a little bowl that holds about 1/4 of a gallon(not my choice, I wanted him in my empty ten gallon aqaurium but my mom didn't want to buy the things needed). After showing her that right now he is too the point of almost crawling out of the bowl, she has decided to buy the things for him.
I need to know what I need, I will provide a list of stuff I have and I'm going to be buying, I'd like to know if I left anything off or I added something not necessary.
Okay I have a 20 gallon aqaurium and a turtle dock, I'm going to by a
UVA/UVB bulb
a clamp for the bulb
a screen top for the 20 gallon tank
submergable heater
submergable filter
Now I also have read that I need a basking bulb(any 50watt bulb will do), would I need to get another clamp for that bulb?
I also would like to know if I need to place the clamps above the aqaurium, I mean another wards where do I place them, I don't want to overheat the water. What's a safe temperature for keeping the water at, like 75?
Thank you.
