First mistake...
I didnt read up on goldfish.....I simply asked the woman in the petshop. Who
obviously knows very little about goldfish and the care of them.

10 x 10 galons ....100 galons ...= 378 litres ?
Jeez thats a huge tank
are you sure thats right for each goldfish ? what about the size of
goldfish...mine are only 2 inches long x 8 and 1 inch approx for the two
blackmores.

Yeah, they're that size now, but if you do things right, they'll get
bigger, and fast. 10G/fish is about right for adults in the 4-5 inch
range. 29L ~ 8G? You should take 9 of those fish back and get your
money back.
