You're right the pictures are pretty low resolution. I'll try to get some better ones soon. The design of the goldfish farm isn't terribly important though. All that matters for efficiency is fish statues + lava + crabs stepping on pressure plates in a 2x2 box. I'll let you work out your preferred design on your own =)
