Hello Roger. I have an extra aquarium, in addition to the one I keep fish in that runs 79F. So, I've been kicking around the notion of raising bugs - let's say, for now, caddis since they are hearty. Maybe stones, maybe mays, but I figure that will come with time and experience as they are more persnickety about environment. So, pretty easy for the most part I think, but I have a few questions and I'm sure you'll be the right person to ask as I'll likely end up with answers to questions I didn't think to ask... 1) temperature - how do I keep the temp in the right zone to raise insects? Given that trout streams vary a lot, from really cold in winter to pretty warm in summer, how much does this matter? I'm supposing room temp is a bit warm, mid to high sixties... am I wrong? 2) flow - I want to hood the aquarium and have a filter in place to keep it reasonably clean as well as provide flow. How much flow depends on the bugs, right? I mean, given that net spinners like setting nets to capture stuff vs cased caddis which tend to congregate in slower areas of streams, etc... do I need to have an aquarium set up for a specific flow for specific bugs and another aquarium if I want bugs that are totally different in terms of flow requirements and/or liking? 3) food - um... mainly little guys eat algae and stuff we can't see with the naked eye, right? Do I need to feed nymphs? Do I need to do something to cultivate the food chain in the aquarium? I'm clueless on this topic. If there is a good resource or resources on the web for getting started, my google searches haven't turned them up yet. Perhaps you can either tell me what I need to know or point me the right direction. Cheers!
