I love goldfish, I'm a carpaholic. My tank is 21 gallon. I used to have my 21 gallon in the living room and then a 50 gallon tank in my kitchen. My oldest goldfish I bought in 2005 and he's probably about 7 inches long. I used to use my 21 gallon as my meds tank. I had 5 commons in my 50 gallon and 2 or 3. Then I built my 450 gallon pond 0053.
I put all the commons in there and bought some more and 3 koi. Within a little while the koi died. When I fished them out they had chemical burns on them. I took them to my local aquatics place with a water sample and they said the ph was extremely high. So I drained the pond, turned out some of the sealing paint I'd used to seal the pond had split and the water was absorbing stuff out of the concrete. So I put in a liner. Then put all the fish through a course of meds. Once back in the pond I kept my eye on the para's and bought 3 female English bred goldfish, they are beautiful. They look like submarines in the pond. They are twice the width of the imported goldfish.
One of these Orandas only has one tail so I'm going to take it back. Once I have two fish I'm happy with I'm going to start a cycle of salting the water which treats external parasites. Then I'll do a course of discuss wormer plus for internal parasites. That also treats gill flukes. You should see me in pets at home, I drive my wife mad "that's got fluke, that's got ick, that's got a anchor worm, that's got swim bladder." I also tend to be able to spot the pedigrees that get big quick. 0158
My ambition is to bred them, but the guy in the aquatics place said to leave them in the pond and they will do it on their own. But I want to raise the fry!
