Also even though we've a big tank I hear plecos get very large and take over the tank? Is this true and therefore should we avoid this? Just wanna know what's best for my little fishes! Ta nat

Your small fish will breed, given clean water conditions, but you apparently have room for them. I keep roughly 100 or so Guppies, 20 or so Playts, 10 Cordoras and a couple of large Plecos in a 60 gallon tank with no trouble. I do change out a lot of tank water every week, but that should be done for any tank.
Your tank situation is very manageable.
