Euchilichthys guentheri?

[rommer]

Hi all,

I placed in this topic:
http://www.planetcatfish.com/forum/view ... 13&t=34304
some pics of a death

Euchilichthys guentheri

, as it was identified by Silurus

Now i was able to make some pics of four living fish i got. I was wondering of there also the

Euchilichthys guenther

are some other species

Fish 1 (dark/black one)


Fish 1 and Fish 2 (fish 2 is more grey and looks different), fish 2 is the lower fish who only shows his head


Fish 3 (dark/black one)


Fish 4 (more grey)




First question is: are this fish the same species and are the

Euchilichthys guentheri

next question: Any tips on keeping them (besides the information in the cat-eLog)?

[Silurus]

These look the same as the dead fish.

We have a batch of 15 Euchilichthys sp. landed some time back. Most of them were badly scared and wounded as the shipper put them all together in one bag during shipping. I was surprised to see most of them recovered within 1 week after landed without any medication in the quarantine tank of the shipper.

They are very aggressive towards the look alike fish. I have 2 in a 120g. They are doing well. They took abt 2-3 wks to settle and now actively feeding in the open when I drop food in the tank.

oh ya, I think I have 2 diff species as one with some white markings and broader while the other without the marking near the head area and also more slim on dorsal view.

The only thing to emphasise is that they can be extremely territorial when space is at a premium. Even with good amounts of space they tend to like to want the same spot on occasions (flow, O2 levels?)

And they are very intolerant of nitrate build up - good water maintenance is a must.

I have a single specimen of E.guentheri I got for free from an importer as it came in as a "contaminant" with some wild caught kribs, and it looked in such poor condition the supplier was convinced it wouldn't make it. It was around 1" SL when I got it and astonishingly thin. It recovered very quickly and is now 6" SL give or take, about 2 years later.

As far as keeping goes, it has been generally undemanding, eating just about anything, but is, as others have noted, very aggressive and tough, it shares a cave with a Pseudacanthicus sp. L024 that is about 11" SL, despite the pseuda constantly trying to evict it. I can't think of many other fish that would stand up to such a spiny cave-mate.

Thank you all for the answers!

I got four of them. Number 4 (on the picture) is in a different tank because he looked really badly when he arrived

Number 1 is mostly laying on the wood (as shown in the picture) and number 2 who i believe could be a different species (more grey and a little different shaped) is mostly on the same wood.

Number 3 is as dark colored as number 1. And he lives below the piece of wood where number 1 and 2 are staying (see the pic).

They are almost always on the same place. I haven't seen them eating but a night i feed also so i think (and hope) that they are eating then.

I have seen some little fighting (more pussing away), we shall see how that developt. The tank is 2 meter so i hope they all find there on place and can live together. Otherwise i have to seperate them.

Bringing in number 4 to the tank seems not a good idea? Or do you think i could try it because it's a large tank?
