I went to petsmart, their fish stock is generally healthy, and all of them are usually young with the exception of goldfish. They have a horrible live plant line up though. The petland has a great live plant stock, but has older fish that are pften diseased, if not dying...aquarium supplies are hard to find in AZ! There's also a petland, but I've been told not to go there
About the black and white skirted tetras, the whites are albino blacks, and they have lineups of neon colored white skirts! Do not buy these because it's not natural and they were either injected with dye like they do a tattoo, or placed in a cat if concentrated dye for extended amounts of time. Both of these methods shorten their lifespan (glofish, similarly colored neon fish, are genetically enhanced and the coloring is in their DNA which is carried on into offspring, and are not in any way dyed) the only safe and natural way to color a white skirt tetra is to feed it colored food or dyed food. They generally turn a paler color of the food you feed them, and they have safe dyed foods for tho purpose, but non-dyed foods can also color them. I feed my fish red granules, therefore they will turn a pale pink color within a few days of eating it. I felt a serious need to explain this to you guys because it's a serious lie that lfs' will tell you.
On the current position of the angel, he is sitting dead center, a few inches from the surface, floating in the current. The other fish have pressed down and are preparing to rest for the night, waiting for dinnertime, and so he has most of the tank space to himself
