oscar and polleni

[JonV]

I've got a group of Polleni myself and what I've seen is they do tend to act like the Oscar of the African world really. They do have a tendancy to eat smaller fish if they see them. I made a mistake one time moving a group of Protomelas Steveni's that were about a month old into the larger tank where the Polleni were, and all 62 of them were gone in less then 2 hours. Wasn't much I could do once the carnage set in.

As far as temperment is concerned, that would not be my worry, though Polleni likely grow much slower then an Oscar. Polleni however are a Madagascar species, and their status I believe is threatend. I wouldn't house these two species together due to such a large difference in water chemistry needs. I know my hobbyists will swear that's not a major factor, I'm not of that mind set. I've seen much better results in my African stock by creating as close as I can the water chemistry the species has evolved in.

My polleni cowers in the corner from a smaller midas. He's like 3" bigger and huge looking when they are next to each other. The polleni is pretty docile. I was told they are pretty nasty

It's just a temp. set up while the 240g is getting decorated and cycled.

My oscar is a full 14" and will not tolerate anything that looks like a cichlid.

My Bro used to have an Oscar around 14" in a 110 gallon and it wouldn't allow any cichlids in the tank as well. I would be careful.

i have a 200l tank and am setting up a 310l but am not sure if my polleni which is a bit of a bully will cope with an oscar?can anyone suggest agreeable tankmates for either fish!!

My oscars trashed my polleni :-( but they also trashed my arowana :-(

Erm my oscars are in with a Pacu and a Tiger Shovel Nose now.

And my Polleni was in with two corydoras, a silver shark, a fire eel, two synodontis, two clarias catfish, a filament barb, two sucking loaches, a flying fox, a toad, a red finned shark, a clown loach, a botia loach, a bircher and some form of armoured catfish and he got on just fine with them.

I have moved him into another tank now with a giraffe nosed catfish, a red finned shark, a sun catfish, a clown loach, a pleco, a monochromis and a clown knife and he gets on just fine with them too!

In fact i lied, my Polleni does cower from the monochromis and he is twice the size of the monochromis! That is the only fish he aapears to be scared of! Otherwise he jus swims round showing his authority!
