I started a new thread now that I have gotten my 10gallon tank set up and ready for fish. I now have in my tank two guppies. One is suposed to be a green cobra guppy but he looks yellow to me. Anyway, he is very pretty. And another guppy that the store said was a cobra guppy but I don't think it is. It's got a yellow/pinkish/silver head and shoulders, black abdomen to the base of tail, and a rounded tail fin that looks like a match flame (yellow/orange with black tip). It's a very pretty little fish. Anyone know what it may be? It's definitely shaped like a guppy. Also, I am a complete beginner at this so I got the 10g "setup". I think it's an Aqueon. The filter it came with seems to make a strong current in the tank. My fish are going to keep really fit swimming in it. The water falls down from the filter and creates a strong downflow, so much that my guppies can't swim directly under it. I can't imagine what will happen when I put ghost shrimp in there... they're gonna be swept round and round the way this thing is set up. How do I fix this, or is it supposed to be like that? I just thought of another nooby question. They keep reasting on the gravel for short periods of time. Is this okay? I just want my fish to be happy. Oh, and another request... can someone please post a picture of what an anal fin is, and what a male and female one looks like? I am not wrapping my head around this seemingly simple concept. Thank you! I know I am asking a lot, sorry.
