That's a long time... which might be where the algae is coming from. I get away with 7 hours, because of my BN pleco, and I actually want to have a bit of algae for him. If not, I'd probably cut the time down to about 4-6 hours. Before I got the BN I only had it on for 6 hours, and i always had a touch of algae, not much, but some. I'd clean it off monthly.
Understood about the otos... the key is to keep them in numbers too though. At least 3, I'd say.
The gouramis are only 1.5 inches long (but they can get a little bigger than that), but they are disk shaped, not long and slender, so they are bigger than they seem when only looking at the length.
