About two weeks ago I brought two goldfish, a black Moore and I'm not sure what the other is, basic white/orange goldfish. They have been living in a fish bowl since, I replace the water everyday and know the urgency for getting a proper and larger home for them. They have been doing fine but now that the weather is heating up they seem to be gaping at the top of the water, one does this more than the other. I have an oxy shell and have been replacing their water with much cooler water frequently today and they haven't really stopped. They are not in direct sunlight either, help would be appreciated
