I think the max rule is 1 fish per gallon of water. You will need more algae eaters too. What kind of lighting are you using?2. question fo professional photographers Canon lens?If you've been using your XT for a while, you should have a good idea of what focal length works best for you. My guess is something like 50mm. If you want better image quality in that range, you coud pick up a Canon 50mm f/1.8. These are fairly inexpensive and you can use a larger aperture than with any zoom lens. But a zoom lens - even the 18-55mm kit lens - should work nicely until you have specific reasons to upgrade. Also pay attention to how other portrait photographers use lighting. This is at least as important as buyng a better lens.3. how to get the best video quality out of canon dlsr?It's not a question of "the best setting." It's a question of understanding exposure, lighting, dynamic range, lens quality, which aperture to use, etc. etc. etc. In other words, go learn the basics of photography and the basics of cinemaphotography -- then your video will improve. The camera is quite capable of stunning video, but you need to know how to get it. Peace.4. Can seeds from store bought ORGANIC fruits and vegetables be planted to grow your own vegetables or fruits?As others have said, just avoid the hybrids. They do not usually have much flavor. You want to look for "heirloom" seeds. These are the ones that usually have not been altered in some way. Some of my favorites are not heirlooms at all, but if you are inexperienced, that's always a safe route. I get my seeds from locals I trust, from my own plants that I've harvested, from nurseries, even sometimes from Home Depot, because I've come across some great ones in hardware stores (not always, but consistently). You can even try places like ebay, at least as long as you trust the source. (After all, anyone can claim they are growing organic/heirloom/whatever seeds.) If you are going to grow indoors, though, you need to consider germination temperatures and lighting. Some peppers require higher temperatures to germinate. Other seeds need to be frozen or refrigerated first. You also need to consider your climate and whether or not you will be moving the plants outside. If you are going to do this often, I have some suggestions for indoor lights. Feel free to email me if you need help with anything. I've been starting my plants indoors in many different climates for years.5. Do you look different (bad lol) in certain lighting, like fluorescent? BDD?When a person has BDD, things like lighting can make them see a completely different person in the mirror. The truth is, you looked exactly the same without the lamp as you look with the lamp. Some types of lighting can flatter certain people, or make them look worse, but the difference is not too dramatic. If I were you, I would put a dimmer lightbulb in your lamp or get rid of it. Even though others are not seeing what you are seeing, you should avoid things that cause issues with your BDD
