i feel ya there, i dont know ANYONE who has a fish tank (excluding one friend who i cant convince that "your fish only grow as big as the tank they are in" is completely wrong)
You mean to tell me that a comet goldfish won't stay small in a 1/2 gallon aquarium
...just kidding. There has been some interesting views locally on how to take care of fish. The worst so far is 30 fish in a 20 gallon tank and the person didn't know they had to do water changes
. Apparently they had that tank for two years.
I have tried to find a fish club in the area that doesn't involve saltwater, but came up empty handed there too. It is good to know of a couple active members here from the area. Mostly I just end up talking to the owners of the coral reef or pet haven about freshwater.
