I-spy,I had a couple of goldfish for a while..one died,the remains one lived
for a few years..there was no filtration aerators etc..couple of years later I got tropical fish..got all the extras,you name it,they were short of nothing.
They started dying one by one..read all the books,went for advice
everywhere..still they all died,I'll not be trying again..just don't like seeing
little things dying...but I also know some people who've had them a long
time..so hopefully they'll see your thread and give better advice than I can.
