Ancistrus Hoplogenys L-59

[Bjørn]

Hi.
I have a group of this beautiful Ancistrus. I've bred quite a few pleco's but this one is more difficult. Also extremely shy. Any comment on keeping, feeding, breeding this fish I'll be thankful
The parent fish were cought near the village Ourem , and bred in Germany. Mine are F1 of these.
I've had them for 3 years now and I 'have tried different setups. The Largest Male is now 15cm and very rough and killed one of the females, so I decided to eliminate him from the group. I have only 2 females left (5 males) therefor I considering to eliminate 3 other males from the group and remain with 2+2.

It is also a very rare fish - not at all common in the trade.

I'd expect that breeding and feeding is similar to

Ancistrus dolichopterus

- soft, acidic and fairly warm water. As they are very shy, you probably want to keep them in their own tank - possibly with a few swimming fish to make them feel happy.

Edit: And welcome to the forum, I see that it's your first post here.

Thanks Mats

Maybe I should try only one male with to females.
Had the same problem with L-107, too many males.

Yes, multiple males can lead to "fighting instead of loving" in the tank.

The L-59 is cought south of Belém in a clearwater river. Usually found atached to wooden pier of bridge etc.
That's miles away from Rio Negro where among other, L-107 and L-183 is found. I use Oak leaves to lower the pH, but doesn't seem to work with L-59.
I mow have pH 6,2 28C tap water is 6,5 and changing 3 times a week 30-40 % of the water each time. Lowering the temp from 28C to 25C.
So maybe Janne have an other answer !!?

Hmm, yeah, I guess Rio Xingu is not really a blackwater river.

Janne's ideas would be appreciated to me too.

Mats

No, it's whitewater

Most blackwater is north of the Amazon river, whitewater is mostly south. Whitewater fish are much easierto keep, as the water is not that extreme

But Ourem is not on the Rio Xingu!!

it is on the Guamá...

Ah, and I think Guama is more towards black-water - it may not be Rio Negro type blackwater, but going in that direction.

"I would like to restrict the distribution of Ancistrus hoplogenys to the river system of the Rio Guama in state of Para in north east Brazil, to which also belongs the Rio Capim, the typical locality of the species.

Until now no fish anywhere near as prettily coloured as L059 had been found anywhere else in Brazil

The catfish L059 was discovered by Kilian, Ludwig and a few collectors from the firm Tropicarium Para (Belem) in the summer of 1989 in a small tributary of the Rio Guama in the vicinity of the village Ourem. The hunters described this place of discovery as a smallish quite flat clear water river, in which the fish preferred to attached themselves to submerged wood, for example the wooden supports of a road bridge."

From the aricle on "The White Seam Bristelnose"

I have 2 female 10cm and wonder about wich male to go with them. ? I`m afraid to put the biggest male16 cm in because he allredy killed an other female.
I will first try with an 12 cm male.
This atempt will be a trio.

Nice clutch of eggs today This was a great success, but as usuall the first breeding often ends with just a nice meal for the male. Let's hope the eggs remains for the next days.
But I saw the other female also with eggs...ready for next breeding already.
Feeling great now, it pays to be patience
Bjørn

[Bjørn]

just as expected, the eggs were eaten...
I guess there will be a new clutch of eggs in a few days.
Bjørn

[MatsP]

I think that's fairly normal, and best of luck for next lot.
