Thanks guys!! All input welcome....its such a mine field for stocking. Don't want to make a terrible mistake out of lack of knowledge.
Yes, I'd been looking into Amano shrimp instead of the otos, they are low waster producers also I think. I've more reading to do. I liked Ghost shrimp too, but they are not algae eaters apparently, more ground waste eaters.
I'd been told about the draw backs of Dwarf Gouramis in that they are very sickly fish....Honey Gourami might be more hardier perhaps? Or I'll go for a different fish altogether...just one if I can get away with it.
Anyway...I've some more reading up to do alright. If I'm going to put anything else in this tank, it won't be for a few weeks. My tank only stabalised in its cycle this week.
