YOU'VE GOT TO DO AN UPDATE VIDEO WITH NATT! It's been over a year, and it's my favourite video on your channel😊

that magenta is ABSOLUTELY insane

damn all that green water is just filled with daphnia, infinite food

those endlers are crazy!

I have been watching Ivan's Guppies breed a stable line of completely white guppy with an iridescent head. Fascinating to see the crazy result this guy is getting with the snow white. They should do a collab video for sure

he does it the way i would!  Amazing!

I have a full uncapped abandoned well in my back yard full of Guppies. Looks great when the sun hits

Glenn there's a guppy strain that looks strikingly similar to purplish blue ones you've created. It's called the purple luminous guppy. It's clear that strain also carries the magenta gene as well as some snakeskin pattern, which from the look of your females, your strain carries as well. The magenta gene has some very weird interactions with any snakeskin pattern. Magenta will almost completely wipe out the snakeskin pattern in the body and sometimes, but not always, in the tails. The resulting guppy body color can be that deep blue to purple you see in your guppies, although red color can remain in the fins. Since there is no red expressed in those guppies, one of the genes from the snow white guppies may be suppressing any red coloration in the fins and perhaps the whole body. Purple in guppies results from a mix of red and blue color cells, so why red is erased in the fins but some still remains in the body is something I can't explain.

I absolutely love those opal endlers!!!!

Amazing video and presentation

Definitely the most comprehensive aquarium channel out there 👍 All you Ozzie guys are nailing it

the dudes a god!  Amazing!

I put all my Guppies from the two tanks at the school where I teach and my 55 gallon tank at home and put them in my pond on my front porch. Their colors get so much brighter and they seem so much healthier and happier. When I take them back to school they look so much healthier with brighter colors.

Glenn! Always a pleasure! I’m hoping Nick eventually convinces you to make long form videos. Each one would be so good!

Y'all are making me want guppies, and I never really thought they were that interesting before XD

YES BROTHER THIS IS EXACTLY WHAT I WAS LOOKING FOR!!!!!!!

Omg first time I’ve ever seen so many different types of guppy’s so beautiful x

Great video, Glen is inspiring....almost a "fuck around and find out" attitude to breeding things he likes. Superb! some stunning fish

We need more guppie fish room tours, and an update on natts room!!! Keep up the great work!!

I’ve just recently gotten way into the Medaka. I’m so happy to see Glenn keeping Medaka. Very much looking forward to the future videos with Glenn.
