Can you share the recipe that you folks use especially for Omnivore fishes. West african dwarfs in perticular.
Note that i am taking of smaller tanks in here as explicitly mentioned above and not bigger tanks.....

I don't rely much on BHM, except for discus and even for discus, only if i don't get live blood worms. The fishes you've mentioned can do absolutely well with bits may be you can add tubifex/blood worms if you have access to them.
Tubifex/Blood worms for invariably all small omnivores/carnivores, prawns for bigger carnivores & blanched palak for africans (Fronts & Duboisiis). This is what I feed them mostly, not to mention a supplement of pelleted/bits/stick food.
And AFA your experiment is concerned, just try to do the same in morning or even better noon, to make sure it is not affected by atmospheric temp.
Madan just on a different note here, Do you mean to say that we can just directly add an ice cube into a water and still will not have a change in temprature in a small environment, I think otherwise. Note that i do not have a thermostat on my small tanks. 300W heaters what i am talking about are there in my bigger show tanks.
Depends on the size of the ice cube. If it's 300 cc in size and the aquarium is 10 liters the calculations vary.
1 CC volume frozen food will not cause any perceptible rise in temparature.
Feed the fish a 1 CC frozen food cube and check. They will gulp it down in 30 secs. low temperature or what ever.
I don't know what you did and how you measured the drop of 3 Deg C, in roughly 40 liters of water, just 3 cubes of about 1 CC each cannot cause this high a drop in temperature. Physics of heat transfer is the same everywhere, it does not selectively change from place to place. It is a function of difference in temperature and mass. The mass of the surrounding water is many times the mass of the frozen food.
Don't believe anyone here. Read up any Std. 10 or 12 Physics book. You can calculate everything for yourself. Google will give you all the fundas you need to check this.
I guarantee you that the change in temperature will be so minute it will not be measurable with any aquarium equipment.
