Info on Merodontotus tigrinus?

Greetings All.

I have just visited a fish shop (about 300 miles away) and the had several Merodontotus tigrinus there, the first one that I have seen in the flesh as it were. Although i am not thinking of getting one at the moment

, as i do not have my fish house built, i was hoping that someone could give me some more info on this species such as total length of a mature fish. I have looked on the Cat-e-log but there is not a great deal of info there.

Thanks

Tristan

And greetings to you too.
The books are very careful on the TL of this species.
Burgess doesn't give any clue; Mergus 4 states at least 50 cm. However, I've already seen a 3-footer at an LFS in Amersfoort, Netherlands. I couldn't tell you for sure whether this is a full grown animal or not.

Thanks

The largest one that I have seen is 2.5feet, so any advance on 3feet.

Thanks

BTW I found this on the their size on Scotcat

The show size listed in the Catfish Study Group U.K. listing is 450mm s.l. i.e. from the tip of the snout to the base of the caudal peduncle. In their natural habitat, however they grow well in excess of this size and can attain lengths in excess of 600mm quite easily.

The one Marc's telling about is NO WAY 45 cm to the base of the caudal fin.....

I do realize fish in tanks often look bigger; but this is really a "Tigershovelnose-size" monster or at least very close to that size.
2 feet at least, but I think quite a bit bigger.

maybe next time I'll bring my camera and ask Michael if I can take pix?

Therefore: 3 feet (approx. 100 cm). What's with your reading? -)

I don't think that fish is 1 meter!

big, yes, but not THAT big.

neither is it as small as 45 cm or close to that.

next time I'll bring a cm-measuring-thingy as well

Thanks for the links, Stunning rays as well, My LFS recently had a jurensis in with a motoro and teh motoro bashed it - the sting to the head killed the fish within 2 hours

, would you keep a tigrinus with a stingray

Do you know of the likelyhood of any problems

Thanks

Aside from any discussion on size, stingrays are not fast water fish, tigrinus truly are.

I never had problems when I was keeping tigrinus with rays. Don't have them any more,,,some old pics

Barthem and Goulding, "The Catfish Connection," list 50 cm. This fish is not listed in either Romano's "Los Bagres" or the Colombian Red Book.

are the tigrinus catfish very sensitive to high nitrate levels, and how often should i feed?

Hi Tristan,

I have a 13" Jurensis in with my stingray's and 1 of them is a 16" Leopoldi, they've never had a problem together. Granted every so often the Leo's swim over and land on him but he just throw's them off, there's never any aggression.
