help on anole lizards appreciated!!

i'm not quite sure what to do, safe to say i spent a fortune getting a decent sized tank for 2 anole lizards - as i read that they're better off and happier if they're not on their own.
I bought 2 of the lizards, one is about an inch longer than the other but they're both in reasonable health (considering they only got back from the pet shop the other day), the only problem is that they seem intent on attacknig each other.
I know (after he raised his flap at me) that the larger one (Thor) is male, and i have a suspicion the little one (Loki) is also male.
clearly Thor is the dominant male, but Loki wont give up and despite his size he fights back.

I really cant afford to buy another cage and the lighting and heating for it, is there any way at all these 2 could live together? or am i best to ocassionally give Loki some respite from Thor?
