It depends on the species. Most pairs are happy, and will spawn, in a ten gallon tank. For larger species a 15-20 gallon tank should be fine. That said, bigger is better and 40 gallons is probably about ideal for a pair.

I'm assuming you mean a pair each in 4 ten gallons, not 8 4 inch fish in a 10 gallon tank...
I initially spawned my bristlenose in a 10 gallon tank, but found that its far too difficult to maintain optimum water quality for fast growth rates, even with moving the pairs with every spawn. The fry just need too much food for the water volume to handle, IMO. I use 20 gallon long tanks for my breeders now, and I remove all but 1 spawn from the tank to grow out at a time. It takes them about 3 months to reach 1.5" TL this way. Otherwise they can be quite slow growing, IME.
In a 40 gallon tank you could raise two or three spawns at a time with just a couple 50% water changes a week, without a problem, I think. I usually give any tank with ancistrus fry in it a 70-80% change twice a week. It does seem to make a noticable difference.
Hope that helps
