why do I see different synspilum names? i.e. paratheraps synspilum, vieja synspilum and cichlasom synspilum. As far as I have found these are the same fish. Am I correct in assuming this or is there a difference? Sorry if this is a dumb question but it's kinda confusing me a little. If they are the same what is it's actual name and why the variances?
