Can I put these in a 20 gallon?

Can I put two Blue Socolofi and two white socolofi in a 20 gallon tank?

 

[Cichlid-Man]

No. They grow to large....to about 6".

No. Also too aggressive to work in that tank.

well even if you had a massive tank I would be concerned about crossbreeding. the blue and whites are the same species yes but they are from different catchpoints and mixing different catchpoints is generally frowned upon in the african cichlid hobby.

....
even though it happens all the time in the lake

and a 20 is only good for fry until they are 1". min for africans is at least 55.
