Hello, I'm new to everything fish-like: Aquarium care, cycling, fish care, ph, etc. So I'll just start the story of how I got to where I am in detail. My dad gave me a standard 10 gallon tank, 3 serpae tetras and a plecostomus. I got some small pebble like rocks as the flooring, and 3 plastic plant decorations. This is my first time taking care of fish so I read online about serpae tetras then saw that they needed to stay in schools of 5-6 or more. So I got 3 more. A week later, I noticed my fish not swimming around the middle much but stayed fairly low in the tank. They didn't seem sick, they actually look a lot better than from when I got them from the pet store. Fuller fins and better color. I thought it was the lighting, so I made a light cover to dim the light a bit and moved around the decorations. After that they started to swim around more, even to the top! They seemed fine for awhile, but they were picky about the flakes I gave them. They favored only eatting the red flakes from my multicolored flakes. After some time I went out and got 3 more serpae tetras (9 total) and Omega One Super Color flakes (because they're reddish). Another week passes, I noticed my fish seemed very scared and jumpy. So I made a background out of construction paper so they'd feel more secure and safe. Waited about a week then I changed the rock flooring to some gravel. Now the fish seem to being doing fine, they swim around, and chase each other. Here's my problem: My dad's serpae tetras in his tank don't seem too scared when i walk over, He has 5 in a 15-20 gallon tank? with a bunchload of other different fish. But, my 9 serpaes are very timid and are scared easily especially when i walk over to feed them They'll group up at first, then notice food and then just feed. They don't freak out when I sit next to them and watch them, but when I walk over they group up immediately. They're most likely stressed right? From the gravel changing, to the lighting switch, adding new tetras and decoration adjustments. -What can I do to help them not be as easily freaked out? Maybe I'm just freaking out. Should I just be patient? I think I've done all I can do. -How do I get my serpae tetras more red? -Do I have too many serpae tetras in a 10 gallon? (9 total) -Can someone give me a better description or pictures to tell the difference between male serpaes and and female serpaes? More colorful, less colorful and fuller body just doesn't really paint the picture for me. I've done more reading in the past weeks about these fish than I've read in 4 years. A lot of websites say that serpae tetras are easy beginner fish. But they seem like they're fish that gets easily stressed. "They're stress is giving me stress because they're stressed." I just want them to be happy. I feel like I should just give my fish to my dad and get a betta instead. But I enjoy watching a bunch of little fish run around and chase each other in a tank, not one that just floats around. and now I'm here, thanks for reading.
