GOLDFISH... this was of course before i started doing some real research on this website... so i went out today before i stumbled on this site 4 tiger barbs and 4 mollies.. (i'm such a noob). Seein as how i heard that goldfish are just unhealthy fish in general, do i have to worry about my water bein unhealthy water for other fish? like bacteria that the nitrate and ammonia tests don't pick up? do i have to worry bout ick or fin rot because i cycled my 20 gallon tank with 2 goldfish? i did a 40% WC when i got my new fish today so i dunno if i'm ok or not... dang i am lost in this new fish world. someone please :help:
