black shark

[landonc]

I purchased a 6 inch black shark about a week ago to be housed with my 12 inch black pacu, he is doing great and feeding on a wide variety of foods. Has anyone kept Black Sharks in the past? Im also needing to raise the temperature in my tank to 86f for a few weeks, should this be okay? Im doing this due to a small ich outbreak on another fish.

Hes very fast but here are the sucky pics :)

Any info??

Nice black shark m8, ive got 2 black sharks 1 around 12in and 1 around 20in (pic in my avatar) they max out at 24in and can be very aggressive i think it depends on the individual fish as my large shark has killed 6/7 fish in the past inc cichlids big cats and other sharks but my smaller shark is not as aggressive as the larger one.

I would be vary as your shark gets bigger watch out for him rasping on the sides of your pacu as this is very common.

As for raising the temp i think that would be fine as long as theres plenty airation in the tank.

That's a great looking Morulius chrysophekadion. Awesome pickup. These guys get pretty big. Ultimate size seems to depend on where the sharks were obtained. Wild sharks vary from 12-24". The same species of black shark, cultivated for food, can reach up to 35".
I had a near 2 footer about 25 years ago that tolerated nothing else in his tank. But, I've heard of other people that had large mellow individuals. Just keep an eye on how yours treats his tankmates.

The black shark I used to have was VERY agressive... It simply would NOT tolerate my Prochilodus, and it even fighted with my Cichla temensis. Every time it made other fishes flee away, almost always with torn/ split fins. But it's a great fish. I really loved it.

Best regards.

Can you tell me were you got that info? have you ever seen proof of a specimen getting to that size? its the first ive heard of it, how can a captive bred black shark outgrow a wild shark?.

I would love to see a 35in black shark btw if they did reach these proportions.

[Cichlas]

Yeah, I'd be interested in the details for 35" specimins. I have one that is around 22" and is pretty aggressive. Fortunately, she is slower than the other fish so they get quite a lot of aggro but they can normally outrun her even under a sustained session.

nice pics u got ne of the 12 inch pacu?

This may surprise you but, I actually look sh1t up...er, I meant to say 'research' prior to posting unless I'm relating personal experiences.

From: The Mekong River Commission -

"Morulius chrysophekadion is one of the large cyprinids. The survey confirmed its distribution throughout the basin, from the northernmost stations in the Lao PDR and Thailand to the southernmost stations in Bassac and the Mekong delta in Viet Nam.

There is some variation in the maximum size attained by this fish in the four countries. In Viet Nam, maximum reported size of Morulius chrysophekadion was 40 cm (16"), while in Cambodia and the Lao PDR it was 70 cm (27"). In Thailand, fishes of 90 cm (35") were reported (about 7 kg), which is considerably higher than the maximum size of 60 cm (24"), reported by Rainboth (1996)." © 2006 Mekong River Commission.

Just searched and found the article. Interesting read. I'm still not convinced myself. Fishbase has the max size listed as 90cm also, but take a look at the pics on the fishbase page for the chrysophekadion and the two biggest ones on there are not chrysophekadion. I suspect that this mis-identification could well account for this size difference although I'm more than happy to be proved wrong :)

Dont be such an upperty twat! i asked were you got the info you provided it, end off.

Btw iam with chichlas on this mis-identification is most likley what has happened.

[slammer]

Oddball has provided evidence to support his position...your only posting opinion. Do you have any evidence to support you? I am very curious about this because I was also under the impression that 24" was about max. But I am not gonna dispute Oddball unless I have soomething to back it up. I think some research is in order.

That's just perfect. A 30year old feels he has to call me names. All I ever did was answer a question.

I'm not sure who you are referring to but if it was me then the evidence I presented was in fishbase. I'm not disputing what he says, but there are thousands of sources that say 24", and a couple that say 35". A "reported 90cm fish" from a fisherman is not evidence, pics and documentation is. So I am sticking with the mis-identification opinion as demonstrated by my evidence :) Although as I have already said, I am quite happy to be proved wrong when I see a 35" specimin, 'cos for me, one that big would be the mutts nuts.

Sorry for being a little harsh oddball but i thought you were a bit sarcastic in your responce!

As for there being black sharks growing to 35in i think we need a lot more evidence.

[Oddball]

Man, I would love to see a 35" solid black shark cruisin' by in a monster tank. That would have to be a surreal and gothic looking spectacle.

:iagree: :thumbsup:

There are several pond/pen raised fish that get bigger than the average wild ones (or at least bigger, faster), Butter cats, channa marulius, and zilli tilapia are reported to do this. the reason is fewer parasites, less predation, and a diet designed to maximize growth. Please note that they are pond or pen raised, not grown in fish tanks. Domestic goldfish and koi often exceed the wild ones in size due to long term selective breeding

[jazzsprstr]

How big is the tank you have them in? I'm assuming since you have a Pacu that it's fairly big. If not, then think about it.

[drewgodat]

nice one there

[snowdrift2001]

Cool looking shark!

[FranchizBoy16]

Nice looking black shark.....Just about the same size as mine....
And what do you feed your black shark?

[Cichlas]

And what do you feed your black shark?

Mine gets Hikari Cichlid staple, Hikari Cichlid Gold, Algae wafers, Tetra-doromin, prawns, whitebait, smelt and occasionally cockles and mussels.
