The bowl is 2 inches in height and the fishes are 3 day old baby fish & the bowl is 2 1/2 in width. And theyre Red Mickey Mouse Platy fishes. n_n so cute & small!!!
The dimensions you have given describe a cup, not a bowl.
The fry should be kept in a heated tank with a sponge filter. If they are kept in a small space ammonia and nitrates will build up. The ammonia is lethal, and the nitrates inhibit growth. Being kept in that space will be very unhealthy for your fry.
