Four Lined Pictus Catfish in my community tank

HI guys, recently picked up two Four Line Pictus Catfish. I was told they were good for a community tank and would grow to 5" by the LFS. I usually find my LFS to be fairly accurate but I think they may have gave me some wrong info. I'm reading in most places they grow to 12" and will eat all my black neons. They are currently 4" and fairly relaxed at day and very active at night.

I have a very peacful 90g planted tank with 4x Bolivian Rams, 1x Geophagus Braziliensis, 1x banjo Cat and 12x black neons.

Does anyone have experience with these cats? Should I be rehoming them before they grow to large for my tank? If I keep them will they cause stress to any of the other species I have listed? Or perhaps they will dominate?
I like these fish but was after a species that would grow to about 5" and be a addtion to my South American themes tank. Any thoughts would be apriciated.

Thanks
Liam

 

They can get to be around 10" and will eat your fish

 

Okay thanks, rehome them. Would any Catfish be good with Black Neons? Such as the regular Pictus?

 

The other pictus might eat them too, if they can fit in their mouths.

I would add more Geos and more banjos.

Brachyrhamdia or bumblebee cats stay small with small mouths

 

Porthole cats would be a good replacement for the pictus. Very peaceful and cool looking fish.

 

Thanks I will look into those species.
