I can give you a few tips ,
most plants will be destroyed , they eat alot , are really messy eaters and require the tank to be cleaned more often, they move objects around , make sure not to attempt to pet it like alot of people tend to do because you may damage the fish's slime coating, and you might not want to use a glass heater because they like to bite and charge so it could potentially shatter it and electrocute itself.
