90 gallon tank

[ae1979]

I have a 90 gallon fish tank that i want to put one or two dragons in . I did some homework and was wondering what i should do about lighting. What watt buld should i get for a tank this size. Most everywhere i read people are using 55 gallon tanks. I live in FL so my house never gets below 75 F so i dont think that i need a heat pad.
I am new to this i had fish in this tank before this so i have no idea about heat lamps. Also any info on UV lamps in a tank this size.
Just dont want to end up getting a lamp that is too big or small and be forced to buy another one.

Hello and welcome!  A 90 gallon tank would be good for one adult dragon, as long as the dimensions are at least 36x18x18 at the minimum.  It is not recommended to keep more than one dragon in an enclosure, because they are territorial and one will suffer greatly as a consequence.  As for lighting, some of us use a regular clear incandescent house bulb, anywhere from 75-150 watt depending on which one you need to get your basking area to at least 105 degrees.  Heat is mandatory for their digestion. A uvb bulb is needed for their health and induction of their appetites...a good one to use is a ReptiSun 10.0 tube light, not compact.  The compact lights have been known to burn their eyes and cause significant damage.   You do not need a heat pad for them, and they aren't really recommended unless you get lower than 65 degrees at night, and then only stuck to the side.  I don't see that being a problem in Florida  .  Look in the General Care section, and you will find a lot of good information, and in the photo section you will find examples of forum members set ups.  There are a lot of good people here, and even some resident breeders!  We are more than happy to help in any way we can

Thanks for all the great info but I think I need to re-phase my queston.
Like i said i have a 90 gallon tank 48x18x25.
What i am worried about is the over all tank temp. I live in FL my house pretty much stays at 75 all year round but from what i understand this is a little on the cold side. What I was thinking about because my tank is so big to get a red heat lamp to run all the time on the hot side of the tank to keep it about 90 i am guessing. Then have 2nd light to come on during the day to raise the temp up for him in the basking area. I am thinking of using two smaller watt bulbs to be able to do this with.
The main reason why i am so worried is because of how far away the light is going to be in the bigger tank.
I am rather new to this so please tell me if this is a good idea or not.

Thanks

I have one other question. I use to have fish in this tank. I have a few large live rocks that i used in the fish tank. I was thinking of using this at part of the bearded dragons tank as a basking area and or hiding places. Is it OK to use this kind of rock or with they carry bacteria that could harm them?

I reused things I've used in my fish tanks too  .  I boiled them and let them cool off, or you can bake them at 275 degrees for two hours and let cool
