I'm going to have to correct you catfishattack. Fish are not cold blooded, they are ectotherms as we are endotherms. Yes, fish cannot use energy in the form of heat and are alike with reptiles being ectotherms. And just because they are ectotherms like reptiles, that doesn't mean they have a metabilism like them. They would go without food for a weekend, yes. But don't give them the impression that they can go without food a month. That would kill almost any fish I can think of. Be careful what you say.
