Minnows??

[Big-j]

Ok I have a "natural pond" tank set up and collected some minnows from my pond, they all all the same species but look just like gray guppies? Are these fish related or just coincidentally similar?

Do you have pictures?

Monster fish grow from "minnows" if you don't know what your looking at, so be careful.

sound like gambusia, mosquitofish. They are very similar, but not super closely related.

i was gonna say those could be fry.

I'm a marine bio major so I know I'm looking at full adult fish, I also know that all are the same species and body plan and structure are almost identical to guppies, they aren't "monster" fish or fry, some are obviously pregnant, I'm going with mosquito fish, livebearers?

 

[jetajockey]

yep they are livebearers. They are probably the most common thing I see in ditches, creeks, and swamps.

Yeah these are the standard in Arkansas ponds lol you figure they'll breed in my 29?

 

[Big-j]

Nevermind that last post lol I caught the dern things today and I already see babys lol

 

[jetajockey]

lol i was gonna say, they'll probably breed in your toilet if you don't flush frequently.

Well they dropped their babies and promptly died all thirty of them were floating or stuck on the filter intake come morning, the babies are everywhere though probably 100+. I mean I expected some casualties but 100%? That seems crazy
