Hey people I have a 55gallon tank and would like to keep either an axolotl, a mudpuppy or a siren (the largest siren) and would like to keep one of these animals. I am getting excelent filtration system made for a 400gallon tank (i like to over do it with filtration for maximum health of my animals <3) and I want something thats pretty much active I might or might not pay much attention to it during the day but will mostlikely be paying attention to it at night as I will keep its light on but would also like to keep a few fish with it maybe fancy goldfish? But would also like to know which ones the best for a tank that size and is pretty much like a captive bred turtle in personality. Ived succesfully kept african clawed frogs with fish before. SO I want to know about these beasties <3 Please and thank you.

Honestly these will not do well with fish. The goldfish could become a potential snack and introduce disease. It could also stress your caudate and nip at its gills.

No not the amphibians I meant the turtle which was comfirmed it can do well with fancy goldfish as its too slow to catch a fish at all

I'm sort of confused as to what you mean, but generally you should not mix species. See this link http://caudata.org/cc/articles/Mixing_disasters.shtml

Like I didnt mean as in I will mix the amphibians with the fish.
It must haved been a mistake. Only thing I would mix with the fish would be maybe a musk turtle, musk turtles can go in subtropical tanks <3 but Iam thinking. People are giving me information which has been misleading me, so I need to research more on it. In any case Id go with either a jack dempsey in a alone tank. OR perhaps, perhaps one or two musk turtles with Adult Fancy Goldfish (orandas to be exact) with maybe a few snails or shrimps for maintnance.
