Origins: Several types of datnioids appear on the market from time to time. Their Latin names get changed from time to time. We’ll be changing this text from time to time also.

On your datnioides information page, web address http://
aqualandpetsplus.com/Oddball,%20Datnioides.htm, A photo contains the
caption "Young tiger datnioides (Datnioides quadrifasciatus). The
yellow brightens with age." The pictured specimen is not actually
quadrifasciatus, but rather undecimradiatus, the so-called thin bar
dat. The quad does not turn yellow as it ages, it remains silver.
Just trying to make your site as helpful to others as it has been to me.
A: Thanks, Dave. I'll add your info to the page. LA
Yellow Tiger: Quadrifasciatus (quadri = four, fasciatus = bars) theoretically has four black bars plus one thru its eye. From this guy we probably get the “tiger” in the name. This yellow datnioid (usually “datnoid”) is the prettiest and theoretically grows to two feet. We’ve never seen one over a foot long. Yellow tigers like lotsa salt in their water. They’re definitely brackish water fish.
Silver Tiger: Microlepis has little peltis (shields or shiny scales) and has lots more but skinnier black bars. He stays smaller, costs less, and needs less salt in his water.
Red-Finned Datnioid: Often sold as red datnioids (they are not red) these guys are better known as Mangrove Jacks. They live along the coasts of many continents and grow to more than three feet. Although these guys are called datnioids, they’re not. They just look like datnioids.

Hey I've been browsing your website and you've got some great information. One fish you say that you don't have an I.D on and have been calling it a Red Datinoid. In fact it's a Mangrove Jack. A very renouned sport fish off northern Australia. They start out with that banded patterns and more of a grey colour with some blue on the face and eventually get about 50cm long (20") and I believe have been reported at 22pounds. They can live in full marine, brackish, and fresh, but won't be happy in freshwater for long. They turn a dark red colour when mature and are very aggressive when kept with others of the same species. So they really do need a large, brackish species tank.
Hope that helps for an I.D, here's a basic web page on them:
p.s Sorry if this is old news, I'm not sure how often you update your webpage and being in Australia I don't know much about American business.
A: Hmm. I thought I IDed it on my Datnioide Page, but I might have left it off one of the Miscellaneous Oddball pages, so I'm adding your info. After all, a report from OZ is more official than a report from Des Moines. LA
In bare tanks red-finned datnioids insist on hiding. It takes them weeks or even months to feel like coming out of the bushes. They do their best to remain invisible.
Tiger Name: The “tiger” in their name probably comes from their stalking as they sneak up on their prey. Siamese tiger fish lack the teeth of the African tiger fish, so they gulp their prey whole.

I was looking at your Datnioides page and noticed a fish called an Asian Leaffish. It is indeed related to the more commonly available Amazon Leaffish and is in the family Nandidae. It is in no way related to the Datnioides. Just thought this would be helpful. Thanks!
A: Thanks. I'll add your report to my Datnioide page. LA
Attitude: All datnioids are fascinating to watch eat. They sidle up to their prey, then suddenly open their mouth like a vacuum cleaner. The surprisingly large prey gets sucked in fast.
Water: Add a teaspoon of salt per gallon. You want very clean water in brackish tanks. Their higher pH levels exacerbate ammonia and nitrite problems. Change it frequently.
Likes to Hide: Young
predators prefer to hide most of the time. Plant
grassy plants to blend with their bars. Otherwise
they spend all their time hiding behind your filter stems or heater.
As long as they get their eyeball behind something, they think they’re
hidden. As they grow, they need less
and less cover.
Foods: Feeder fish and feeder shrimp make the best starter foods. They will adapt to different types of worms. They also learn to eat appropriately sized frozen foods and pellets. Datnioids eat best when mixed with eager eaters. Polypterids and silver dollars mix well. Tinfoil barbs and giant danios will eat all the food too fast.
Other Tank Mates: You can mix your datnioids with equal-sized non-violent aquarium residents. Datnioids eat smaller fish and ignore equal size fish.
Territorial: Datnioids accept other fish species, but they argue with newcomers of the same species. The new guy gets chased constantly.
Space Requirements: The more space you give your datnioids the better. You can house the small ones in a 10-gallon tank.
Breeding: You will probably never breed a brackish water fish (except mollies).
Substrate Choice: Datnioids look good no matter what you put on the floor of their aquarium.
Last Word: Datnioids make excellent specimen fish. They grow big enough to make a great display. They have an interesting personality and will eat from your fingers once they recognize you. They are expensive. LA.

I'm here emailing you in regards to your info for the datnioides.
^ You can refers to this for more infos. Different Tigers have different needs. And they're not all Siamese Tiger, they're just datnioides, and STs are just one of them .
A: Excellent poster showing
several of the datnoides. I'd print the poster here, but
it's copyrighted, so I can't. It's put out by
tigercraze.com, the datnioide forum. LA
It appears to be Lates calcarifer -- an Australian fish raised as an aquaculture crop. Fairly expensive for a farm-raised fish.

Yeah it is, just showing you heh heh
Maybe you can try finding online too.
Anyway your fish site is sooo great, I always go there!!
Keep up the good work .
A: I'll keep plugging away. In the meantime, I found a gold datnioide that I'd put away Friday and couldn't find for a couple days. Thanks for the kudos. LA

Siamese Tigers are already extinct in the wild, there shouldn't be more of those :/
Yours look more like an Indonesian Tiger to me, with the more rect. shaped and bigger eyes, and the tail looks more like an IT too :)
A: Very interesting. I'll add your comments to my
datnioide page. LA

just a note on your datnioides page, the fish which was sold to you as a giant asian perch, "Lates calcarifer" is more commonly known as the Barramundi, one of the largest fish in australia reaching up to 1.8 metres (6ft), 60KG (132lb) !
the yellow line running down its face disappears as it gets older until it turns fully silver!
nice site by the way :)
A: Thanks. I didn't know we could get Australian fish here in Des Moines. I'll add your info to my datnioide page. LA
