I have been thinking about buying a 55 gallon aquarium and putting cichlids in it and building a cage around it with a floor above the water and a part the water dragons can get down to it. what are your thoughts on this project. what type of cichlids should I put in there, they would have to be decent size so the water dragons wouldn't eat them but yet not to big that they would eat the water dragons. what are your suggestions on this. thx.
