Where Can I Find Correct Fish Profiles Information

How can i tell which fish profiles on any site have the correct information about the fish? For example i am looking at all sorts of fish profiles through google and it takes me to many web pages but each one of them have a different information on them it gets confusing, can anyone tell me where i can find good fish profiles? Even books all have different intake on it. I have a huge list of fish that i am looking up and the first one i am looking for now is Tiger Barbs

Well, obviously we hope the information here is correct (second tab from the left up the top of the forum).

For the profiles that Byron writes he quotes other sources and he doesn't just make unsupported assertions, so I feel comfortable accepting what he says.

Some information will vary because people hold different opinions about it (like how big a tank a certain type of fish should be kept in) or they have had personal experiences that lead them to hold a different opinion to that commonly held. You just have to do your research and make up your own mind as to what information you accept and rely on.

I agree with what Tanker said... different experiences and opinions make it impossible to find one set of concrete information on fish. In fact, one of my favorite sayings is that there are almost no hard "rules" for fishkeeping. What works for one person is a disaster for another, and everything is also heavily dependent upon your setup and maintenance.

The best thing that you can do is always take what you read with a grain of salt. All profiles (including the ones here) are colored by the experiences and opinions of the people who wrote them, and may have little or no similarity with your own experiences.

Agree with above,when I research fish I am more interested in what water parameter's the fish need in order to thrive with respect to Temp,pH,GH,KH. Usually these fall pretty closely in line with other sites,or books.Water parameter's hold more value to me than opinions on compatibility with other fishes ,for if the water isn't suitable for the fish,, then it's not gonna much matter whether the fish gets along with other fishes.I try to keep fishes somewhere in the middle of their recommended range for the afore mmentioned water parameter's rather than attempting to keep them at upper or lower extreme.
Compatibility takes in a lot of factors,Tank size,types of fish,adult size of fish, temperment with like species as well as other species,areas that fish frequent in the aquarium, Diet, planted or un-planted tank,substrate material, etc.
Some fish get along with fishes they aren't supposed to(or maybe not) when small ,but as the fishes mature,things can turn.
Seem's no matter what those with expierience suggest ,there is always the odd duck that declares..(Well, I know a guy...) or,,,( My fish does just fine, Blah,blah,blah.)
This is where many become confused.
Research the fish not opinion's,,and things are a bit easier in my expierience.

The most important medication in your fish medicine cabinet is.. Clean water.

Welcome to Tropical Fish Keeping forum.

Information on the internet is only as reliable as the source for it, whatever it may be. As I am the author of most of the freshwater fish profiles on this forum, I can comment accurately on where the info here comes from, and that it is likely to be reliable. The information in our profiles represents the summarized consensus of trained ichthyologists and biologists; where there is a difference of opinion from a reputable source, that is added for completeness.

Specifically turning to compatibility issues, one must understand that there is always going to be some variation from fish to fish; just as with humans, different fish of the same species can exhibit different behaviours whether consistently or periodically. This should come as no surprise, since we now know that species can evolve into new species precisely due to such differences in certain offspring. But there are nevertheless some basic traits that each species tends to exhibit. As you referenced the Tiger Barb, I'll use that as an example.

This fish is naturally aggressive; it is in its inherent nature to be feisty, nippy and a "bully" for want of a better word. Within its own species, it forms shoals (groups) and within the shoal there is a pecking order. When brought into close contact with some sedate fish, it will nip fins and can even cause death. These characteristics are in the fish, period. Now we come to variances.

The fish's environment is now known to trigger variances to "standard" behaviours. When this species is maintained in small groups, say less than 8, and/or in too small an environment [under 30g tank] it frequently causes the aggressive behaviours to become more obvious. It may not always be so, but in the majority of cases it will. This then leads us to write of minimum tank sizes and minimum number of fish in a group and avoiding certain other fish as tankmates. Following these guidelines means more likely having success with this species. Not following them means more likely the chance of trouble--not always, but "usually."

Edit: While reading through other threads, I came across this one on Tiger Barb aggression which perfectly illustrates my point:
You really cannot alter a fish's natural instincts or behaviours. The recommendations in the profiles are not made up.

Hope that explains it a bit.

Something we all need to remember: The fish you've acquired was quite happy not being owned by you, minding its own business. If you’re going to take it under your wing then you’re responsible for it. Every aspect of its life is under your control, from water quality and temperature to swimming space. [Nathan Hill in PFK]
