archers take a while to get that long i had 2 in a 38g for over 2 years when i got bored and traded for a discus.... they were only 5-6 inches long
Did they spit? What did you feed them? Meal worms/crickets?
hmmm... I am swapping my mixed Malawi tank up to 180g from the 110g. A 110g is tall enough that you could fashion something with branches up top and still have plenty of room for them to swim down low.
I think the tank is 30" or 31" high (up to my armpit when I try to reach the bottom of the front of the tank, lol). So you could still fill 16" of water and have 14"-15" of air space on top. For filtration, I would try to use one of my XP3 canister filters, but not sure if it could handle the stress of pulling the water up 15" on the intake side. I would think it would work as long as the intake tubes are connected well/glued together (a syphon, right?)
Now if I can only convince Maria that we can keep the 110g up.
