Hello all!
I'm looking for advice or experiences that other guppy breeders may have with the size of tanks that are used for fry growth at varying ages. For example, I keep my fry in fry-nets during the first week or two to make feeding easier and then transfer to a larger tank. I've heard that confining fry in the early weeks helps them grow bigger and stronger with easier access to food. I've also heard some advice about giving them freedom as soon as possible to help growth, like caudal fin musculature.
What do you do or recommend ?
Cheers!

I start my fry in two 5.5 gallon tanks and then separate them when they can be sexed. The females go into a 40 and the males a 29. For some reason I always have more females than males......go figure.

You can see the tanks a few posts down in the video.

Hope this helps.

I'm a big fan of the hang-on-tank style breeders that use air to circulate water through from a larger tank like this. They keep your fry totally safe and contain food in a small area, but have enough circulation/water movement to promote strong tail and fin development. They also provide extra oxygenation for the tank they're on.

Thank you for the advice. I like the hang-on solution, I've never used one of those before. Right now, my main tank is acrylic with two openings in the top, so the hang-on cant clip to anything. I'm going to set up more tanks shortly though and I'll go with the standard tanks for that. I have a 5.5 ready for the fry now, so I'll plop them in there and then separate the males and females when they are old enough.

If you want big and strong guppies, prerequisites are large weekly water changes and high quality foods, e.g. beefheart and bbs. Nothing else makes much of a difference.

Thank you! I've been giving bbs with along with Hikari First Bites and also some varying dry foods that I pulverize with a mortal and pestle. They get bbs twice a day and are usually fed 6-8 times a day with the dry, sometimes more.
I'll try adding the beefheart to the diet. Thanks!

For water changes, I do 10% every third day. Should I switch to 30% every week instead?

thanks for the advice

I do 90% once a week, but I've been known to be a little obsessive about water changes.

That is great! I've got to get myself set up better here so that I can do larger water changes. Our well water is pretty hard and I've been using peat to naturally lower the PH rather than chemicals. It works, but I need more peat and real aging tanks to build up a supply of good water.
Seeing your setup will be nice.

do you use the frozen beefheart in cubes from pet stores? Do you do anything to it so that fry can eat it? like throw it in a food processor ?

thank you again for all of the advice. This really is a helpful group for people like me!

We have a local guy, Chuck Hawks, that has the best quality beefheart around. Chuck is on this forum and post prices often. If you get into the Twin Cities, make sure you place an order with Chuck.

For my tanks with a lot of guppies, I just throw in a chunk of frozen beefheart. It seems to last less than 60 seconds. For my breeding tanks with 2 - 3 fish and some fry, I'll slice off strips with a razor and throw it in. Same result.
