Hi, Steemit !!!
The main decorative fishes for the pond are goldfish and koi carps.
The maintenance of goldfish in the pond is not difficult, they are unpretentious in feed and conditions of detention, if you have properly equipped your reservoir, have established an adequate water treatment system, then during the spring-autumn the fish will delight you with their colors.
I wish you all a nice day and good mood !!!
