who will best join the family

[Cinnoranium]

I have a pleco, a golden gourami, and 4 silver sharks, I want to add a new species to my little community, but I am not sure what type I should get. Right now all my fishes are living together fine, like a family, and I want to get a new type of fish who can be happy with the others and not get bullied or be a bully.

What is it with silver sharks this week? Everyone seems to be getting them. They need a huge, huge aquarium as they grow a foot long.

How big is your fish tank? If it is really large, you can pit clown loaches in there.

Give us the dimensions/size of your tank and information on how long it has been set up, how you cycled it, what your water parameters are etc. and you might be able to get some good information.
Are the sharks mostly bottom, mid, or top dwellers? Tanks in my opinion look very nice when they have a collection of fish that inhabitat each different area of the tank rather than all on the bottom or top.
