Roseline sharks? how many

hey guys i have looked on this forum for roseline sharks couldnt really find a specific answer. i have a 55 gallon tank that im starting and am looking to put in some roseline sharks. i have read that they love the cooler water ( 72 degrees roughly? ) but have heard they do just fine in water temps just shy of 80 degrees... also learned they love the fast current. i have an aqueon 75 in my tank and looks to push the water pretty good. so heres my question... how many can fit in my tank, i dont want to have a ton of them as i want a couple other fish in there as well, but would 4 be enough for them to feel safe in the tank? also any suggestions as to what goes well with these sharks?

I would say 4-6 roselinesharks (we call them torpedo barbs in Australia) would be ideal for your set-up, but NOT many more.
There are many suggested rules on how many fish to keep....inches/gallon, cubic inches/gallon etc. I have always found it best to add a few (the minimum advised for a shoal) then monitor your water parameters CLOESLY and if everything if fine, add a new fish here and there. As always it will come back to the size of your filter, BUT it will also come back to how dilligent a fish keeper you are. Maintenance will be the primary factor affecting what your water parameters will be.

As to temperature and flow rate, I suggest keeping them at the lower end of your suggested range (with the fast flow rate). The waters these fish come from flow very fast from higher/colder grouNds and this is their natural condition. Warmer temperatures tend to speed-up their metabolic rate, thus shortening their life expectancy. It also causes general stress and that is never good.

They are a schooling fish and you need at least 6. I have a dozen in my 125 gallon barb tank. The temperature is 80 degrees. I have not had a problem with the temperature.

We do have this species in our profiles, under the common name Denisons Barb, or scientifically Puntius denisonii. Click either for the profile. There are many "common" names for some fish and we can only use one in the title. Searching by scientific name is almost assured of finding the fish, if it is in the profiles.

All your questions are covered in the profile, and as you will see, this fish has some specific needs.

Byron.

P.S. I combined the two threads as the issue was identical. It is best not to post the same question twice, it causes confusion when some members post here and others there, and you may not get the benefit of all together.

sorry for the mess. ill clean everything up and take more pics later but this is what i have to work with. just built that top. i have not seen anyone engrave anything in their tops so i thought it would be kinda cool. "fish town" just happened to be the first thing that popped into my head. haha

IMO very carefully consider this fish before buying them. The species profile briefly mentions it, but this specie is endangered and it is due to the hobby and over collecting. Due to lack of govenment protection it is still thought to be over harvested. Captive breeding is at a minimum and most you see are wild caught fish. It recently became endangered in the last year Linky.

Please think carefully and research where your supplier is getting the fish from before buying this species.

I fully second Mikaila's comments. As aquarists, we should be very much concerned with conservation of all fish species, and this means responsible decisions along the way.

As for the information in our profiles, you can rely on it as it comes from the highest sources available. My research is fairly exhaustive.

I don't know how many times I have read highly-respected authors who advocate providing what the fish species requires as being the only responsible way of ensuring good health. If a fish requires cooler temperatures, that is what it must receive. It may manage at higher temperatures, but it will be far more likely of a shorter lifespan and health issues along the way. The blue paragraph in my signature block says it well.

I agree with Byron,and Mikaila's views.
Relying on published works as opposed to opinion's, is always a benefit to the fish and the hobbyist as well.(less sick,dying,dead,fish)
Opinion's are useless for responsible hobbyist's interested in providing as near a suitable enviornment as a glass box of water can afford.
Example.. If I were to suggest that most accomplished hobbyist's, and recent literature suggest's that some fishes prefer soft acidic water, over hard alkaline water,out pops those who claim to keep them just fine in anything but what afore mentioned sources suggest.(usually not for long)
If current consnesus is that fish or fishes are not suitable tankmates for any number of reasons often mentioned in published books (hardly anybody does any research),, then out pops those who claim otherwise.(won't tell you how many they have lost,killed)
Opinion's are as numerous as blades of grass on a golf course, and while measured opinion's are a good thing,,it is wise to research several sources and form equally measured decision.
Profiles here with respect to fishes is as accurate a source as you are likely to find, and it would be to your benefit to include this info during your research.
Those who do otherwise,,aren't hobbyist's ,they are fish collectors, who over time/attrition, manage to collect hundreds of fish and kill many more. This I know to be true cause I was once one of those collector's.(says sheepishly)

I would like to "third" what Mikaila31 has said.
However I would also like to point out that the Indian government has put some time and resource into breeding this fish. Still it's very hard (they say) to do, at least for now. Not all fish from India are wild caught and increasingly things are looking up.
I find this situation analogous with the "celestial pearl danio" (from Burma/Myanmar) and this fish has had its ups and downs (in the 6years since it's discovery). 1stly is was popular, then almost extinct, then it started being bred, then new populations were found in the wild and presently things look fine!!
On that note, exellent news that Burma has had (bi-)elections yesterday (a BIG win for democracy) and the country looks to be opening up, but how will they get income?
I hear there is a freshwater seahorse in Myanmar/Burma??????

Many species have been eradicated from Europe and America has a poor record too...still, my country (Australia) has the worst record of extinction in the world. I can not sit in my heated/airconditioned house and dictate to others....especially if they need income.
