I have my little female Tagalong in a 1 gallon hospital tank right now since she's been striped and colorless since I brought her home from the fish store. She got beat up by her soon-to-be tankmates in the bag they came home in, so I was assuming that was the reason for the horizontal stripes.
Tagalong seems active and healthy in the hospital tank, and she is eating well. I was curious if she might be feeling well enough to flare if I put a mirror up to the side of the tank. She took an immediate interest and flared up, then developed vertical stripes on her body. I was concerned, so I took the mirror away and the vertical stripes have faded. She still has her horizontal stripes and seems to be swimming around normally now.
What were the vertical stripes and should I be worried?
