chinese china fish

These two virtually identical fish are made in china as it says on bottom of rear fins, they also have another mark which I cant make out as very faint, they both have curled tails and are 4" each long , I dont know what type of fish they are but wouldv thought a pearch or some other river fish because of their colours , theyre hand painted in nice bright yellow and brown fins and back bluey bottom and black stripes and the detail is very good as most chinese things are, I dont know how old they are but I do know they were bought from a car booty from an old man who said they were his fathers , ive had them around 20 years so could be quite old ??
If anyone knows or have seen similar to these I would love to know more.. :-)
