Guppies???

Featured Replies

My little brother fished some random 'guppy' fish out of the creek at the end of our road in a butterfly net. He is keeping them in my old 10ltank and feeding them this free sample fish food from our local pet shop.

Do you have any idea what they could be?

They are about 2-3cm long and grey, thats all i can tell you from what i have seen of them.....

I will post a picture of them later. (waters to murky right now)

i can almost guarantee they won't be guppies.. they will be gambusia.. an illegal pest fish - you must not keep them nor return them. You now have to destroy them,. sorry!

they do look like female guppies except that their dorsal fin is set further back than a guppy. They were brought into NZ as mosquito fish because soldiers thought they were going to get malaria here!

there are fines if you are caught breeding them or releasing them.... and yes very aggressive. will even turn on each other!

Woah. I just googled them. I think brother is feeding them to our cats...

Cruel, maybe, but hes a 12year old boy so.....

Thanks everyone!

Better feeding them to the cats than him being sentenced for it, I think it's up to $200K and/or 5 years in prison.

Also...Hahaha, Another, "Hey I found guppies in the stream!" :)

There is a trader on TM who I bought a plant from who had a tank of these he was breeding...

not sure why tho

i used to keep those things when i was a kid. apart from the illegal part they make great first fish. they are free, not fussy about food or water chemisty and are interesting to breed. just the problem of what to do with them when you want to move on!

You have to be careful that you are not confusing leopard fish for gambusia as they can be similar to the untrained eye and leopard fish are legal..

ar they sorta like cockabelly? or are they cockabelly? cause i remember that when i was little i used to go to lake wairarapa and catch the little fish out of the stream that connected to the lake back then i didn't even have a tropical tank so now that i think about it these things that i call cockabellys (my parent told me that name) do resemble guppies. :lol:

Cockabullies look nothing like guppies other than both being fish.:)

Leopard fish are illegal?

Gambusia is illegal for sure?

Yes, Gambusia are illegal for sure. That's like asking, "Are you sure theft is illegal?"
