Perhaps BillT or someone else knows something about this type of food?

Adult Zebrafish Diet

It showed up in retail recently. Any reasons to consider it as a supplement/replacement to normal flake food? Not specifically for danios....

Wow. That's a pretty pathetic zebrafish they have on their page. Looks like some weird barb to me.

The feed would probably work for many fish. Probably small pellet size. It is most likely pretty good nutritionally. There is a different guy (Steve Watts) at UAB that is working on optimizing a prepared food formula food for zebrafish. It is a multi-year project that has been going on for a few years.

This company made a prepared food for zebrafish larvae a couple of years ago that has become popular in some labs.

These and other foods specifically for lab zebrafish are probably rather expensive compared to either for fish hobbyists or for general aquaculture (which is very cheap and good quality, but comes in 50+ pound bags with a limited shelf-life and usually a large pellet size.

There used to be a couple of other companies making foods for lab ZF, but they stopped because they were not selling enough for it to be worthwhile for them. There is also a flake food (AquaTox maybe) made for use in tests of things like toxins. The idea being to include nothing bad in as opposed to having complete nutrition.

This is also irradiated to kill anything that might be in it. This is done because there were cases in aquaculture of mycobacteriosis being transmitted to aquaculture fish form food made of other fish (some of which had mycobacteria). Irradiation does not mess much with the nutritional compounds in the food like autoclaving (like a pressure cooker, kills everything) or other sterilization techniques would.

The price for lab diets is high because of the comparatively small market and the ability to charge labs a lot of money.

I use a hobbyist .5 mm pellet (New Life Spectrum) that I get in a small bucket for my small Danionins and a 1 mm size for the larger ones. Some labs use this food.

I also use a series of live foods (Moina, Walter worms, brine shrimp, and black worms).

Thanks Bill,

It is in a flake form, http://www.arthuraquatics.com/publishImages/FlakeFood~~element157.jpg

, and it is not expensive: $40 for 5lb... this is about 20% premium over the bulk food I use.... so I was thinking about trying it, but it would be for a whole range of other fish... OK... I just ordered 10lb of normal flake, will be a while before the next time....

Well that sounds like a good deal Mike.

Zeigler's larval diet is supposed to do a good job of replacing all other larval foods.

I would expect this to be pretty good also.

The picture looks more like a retouched North American minnow or something.
We use a lab diet from a UK company, ZM Systems http://www.zmsystems.co.uk/ind.....ef=Fryfood, we find it excellent as a supplement to the live foods we use for fry. Many species accept it eagerly at the different grades.

Funny enough the very first time I raised danio fry was with ZM (a friend sent from the UK -- I cannot buy it here), and it worked perfectly. I use Sera mostly now, and it is becoming difficult to find too :(

Bill, Zeigler's flakes (top item on the link) actually work for me quite well despite their ill-repute name (not for danios, with my number of tanks I have to worry about the flake prices).
If you want to try the lab flakes yourself, here.
I have not seen their lab fry food available.

Opps. It is Skretting (an aquacultural fish food maker) that makes the larval diet:

http://zebrafish.skrettingusa.com/

The prices on these foods are not cheap you might notice.

 

The larval diet apparently works great. Many labs can eliminate using live foods for larvae completely.

 

ZM has been around for many years and a lot of people in European labs use it.

We rate ZM as I have said, but we have had little experiments a few times with fry of different spp., splitting batches and just using prepared fry foods for one lot, the other using combined foods. The difference in growth and survival was dramatic.
Obviously in the ZF breeding labs they want control and consistency.

Another thumbs up for ZM foods, although never used it to raise danios.

Cake or death?
