I just got a WTF for my 10 yo daughter, we have him in a 5 gallon, but soon to get a 20 gallon for him. I have an UTF heater ( which isn't heating it at all ). I had some left over large aquarium pebbles so I used those for the substrate. I have a grapevine for him to crawl on. I cover his tank with a blanket on the top and two sides. humidity is usually around 50% the temp is only at 70 during the day with the UTF on the side of the glass. Here are my problems.
1. How do I do a better job of heating him up or is 70 ok.
2. Is the aquarium pebbles a sutable substrate ( too big to eat)
3. He used to climb ( the first week ) on the glass and the
grape vines, but now he wont.
4. He ate great the first three day's and now he wont eat at
all.
5. His color is beautiful, green blue, bright and he will sit on
my hand or my should for hours without moving ( he sleeps )
Is sleeping ok?? He is in the water dish daily and nightly.
Am I doing this right or semi right for the first time, I can't go all out but I do want to keep him healthy & happy.
