I would not trust my Water Dragon with any fish. She goes after anything in her water edible. I would also be worried about missing toes, and tail like you said fishfreak2009.
beleve it or not. the basalik lizard never looks at my fish. never showed any intrest in them at all. The pbass do look at him when he runs across the surface. But havent had the lizard eat a fish or fish try to take a bite out of him.
