Hi all,

Was not sure if this post should go here or in cory section, but as robinae have been mentioned here recently, plumped for here.

I have a 6' x 2' x 2' tank, well filtered with 2 huge eheims. It is pH 6.5 - 7, soft water, temp 26.

River sand substrate, bunches of Aponogeton spp, anubias and java fern on bogwood pieces.
Current tank occupants are 2 groups of juvenile Red head tapajas geo's and geo daemon, some congo tetra's and demonsi barbs, pair of festivums.

Bottom dwellwers, 3 juvenile L128, couple of 2inch home bred bristlenose and 4 young opsidoras.

I was thinking of a group of Brochis multiradiatus, but corydoras robinae have really caught my eye.

I know they grow larger than alot of cories, but my concern is that the water may be alittle too soft, alkali, or that the geo's may be a bit boisterous

Your thoughts would be greatly appreciated

I do wonder whether this is a good idea, as both Geophagus and Corydoras live on the sandy surface

Grophagus are hungry eaters, and C robinae eat a lot slower - thus increasing the risk of starvation.

I've kept both C robinae and Geophagus, not in one tank, and I would not recommend this combination.

I would recommend keeping C robinae - perhaps together with -similar tail pattern, both coming from soft, dark water, and both being rather shy - or Geophagus

I have exactly this combination in my RIO400. I've not had any problem with the Corys not getting enough food. But I have do admit, I probably feed a bit more than most people do, in general.

Jools also has some of my previous group of C. robineae that I sold some time ago, and they were in a tank with eartheaters for a couple of years if not more. They grew nicely.

Many thanks for your input guys, much appreciated.


The geo's are young at only a few inches, so if the robinae are big I may give it a try. I have another mature 4 foot tank with sand substrate and no large fish in I could always tranfer the robinae to if they look like they are going hungry, they can keep the cory sp venezualan group company in the alternative tank.


Thanks
Stu

The advantage of more than one tanks: you can try something, and if it does not work out, remouve fish.

With 1 tank this is hard to do when the local petshop is closed
