Goldfish can be divided into two broad types singletails (often referred to as commons) and fancy goldfish. The difference between common or singletail goldfish, and fancy goldfishĭifferent tank sizes are often quoted for common or singletail goldfish, and fancy goldfish. Poor accommodation and inadequate care can contribute to them failing to reach their true potential, but it is unacceptable to deny an animal an appropriately sized home, and the right amout of food, in order to keep them small. There is a lot of out of date thinking surrounding goldfish and it’s high time they were given the understanding, recognition and respect that they deserve.

I cannot stress firmly enough that you should not believe the ‘ grow to the size of the tank’ myth.

GOLDFISH AQUARIUM FISH FULL
I’m hoping that my experiences of the problems caused by inadequate accommodation, and my experiences of keeping full grown adult goldfish, will help others understand the needs of these large fish and help avoid heartache. I’ve also been fortunate to have been given goldfish who grew into stunning, and very large, adult fish. Having taken on many ‘adoptees’ I’ve seen the terrible health problems and stunting caused by other peoples’ poor care and lack of understanding of their goldfishes’ needs. I have a particular interest in goldfish behaviour and ‘psychology’ they are remarkably interactive and individual creatures and often exhibit interesting behaviours. On a personal note, I’ve been keeping goldfish for many years now and have had the delight of sharing my world with nearly forty of them in that time. It’s something we feel strongly about at INJAF as goldfish are a species that suffer rather more than most when it comes to misconceptions and poor information regarding their care.

What size tank for goldfish is a question that often arises on fishkeeping forums and usually results in a wide variety of opinions and suggestions.
