Intro myself. Im Murray, have a pond in our garden that didn't have any fish in. I have since added about 13 fish, including 3 Koi's. They have just had babies. Not sure if they are Koi babies or Gold fish babies. Im no expert on fish but falling in love with them. Ill be asking loads of questions and look forward to sharing my fish and pond stories with you.

Welcome @Murray !

How big is your pond? Hopefully someone advised you when you bought koi that they grow very large very fast! And you most likely have goldfish babies, as they breed easily. Post some pictures and we'll help identify them!

Welcome to the forum @Murray !

Nice pond!
I would just keep goldfish, your pond looks too small for koi :)

Such a pretty pond! I agree w/ @Gemma the pond is sufficient for the goldfish but koi will eventually get too large. I'm sure someone could be found to give them a good home when they grow, otherwise I hope you like digging a new larger pond :)

I have a water pump and a UV light in the pump however I don’t have a filter. Is a filter imperative ?

Using a quick calculator your pond is around 3 feet deep and 6 feet wide, long. Plus minus, That is around 1000 us gallons which could support one koi with GREAT filtration. They are a lot dirtier than gold fish and need good filtration.

If you want to stay with no filtration, gold fish can handle that.

Thanks so much addy1. So there are a lot of different gold fish in the store, must I make sure they are for outside pond use or can I put any gold fish in the pond ? And should I put Algy eaters into the pond as I don't have filtration ?

Hi Murray, yes nice pond and glad to hear you are bonding with your fishies! I myself was surprised to learn how aware and interactive they are - they will recognize who feeds them and Ive heard of people who actually can reach in and pet their fish!

Koi are large and rambunctious fish, that can grow almost a meter long.... so right there you can see they wont work for a 2 meter wide pond. Its a myth that fish grow only as large to fit the container. The recommendation for koi is minimum 500-1000 gal per fish and a minimum of 4 feet - they need to be able to dive and move freely for good exercise and health. Plus, its just simply more pleasant to watch fish if they can move around in a school. For goldfish its 50-100 gals per fish. A lot depends on your set up and filtration capacity though ( you don't have mechanical filtration but your plants are essentially serving the same function as a filter would. )

Comets and shubunkins are good hardy fish that are good for ponds - looks like that's what you have. They can have different unusual colors and long fins, and closely resemble a koi - except theyll only get 10-12 inches, not 36!

I have two Shubunkins in my koi pond, they have red and blue and are just as beautiful as my koi. :)

These are my Shubunkins! Most people think they're koi because they are huge!:)
