Tips on feeding slower fish

[zebradanio]

I got a oldish Gourami who is about 4 yrs old , he struggles to eat as much as he should because a lot of the other fish are faster than him (zebra danio , five banded barbs) , I recently upgraded to a 240 litre from 90 litre and the danios love the extra space seem more hyper than when they were in the 90 litre
So has any one got any tips on feeding slower fish.
Here's a pic of the old bugger .

is the tank long? if so it might be worth dropping some flake food at one end to keep the faster fish distracted and then a little bit near the gourami. Maybe try a couple algae wafers or blanched spinach clipped to the side of the tank somehow. I generally used to boil up a batch of spinach, red pepper, haddock and garlic, blend it together, bend it with gelatine and then use that as a little feeder (its a frozen food block recipe that works really well). Let it sit in the tank from morning til evening before taking any left overs out. i can guarantee hell get food from that.
