Acquired: Fish / pet store
Posted Jul 07, 2013
I own 3 head and tail tetras. Fauna, floral, and Merriweather. I bought them because I wanted an inexpensive fish that schooled. $13 for the 3 of them. Reviews on them say they are easy to keep but first owning them was a little stressful for me. I don't have a heater for my tank and the clerk at the store said nothing about them being tropical, as I later learned from another clerk a few days later. My fish didn't want to eat for the first 5 days and I started getting concerned. Their black spots behind their gills even faded away.
From what I guess it was the water temperature and the stress of moving from their large school to a school of just 3.
After moving my tank to a warmer place in my house and getting a few more fish in the tank they perked up. Even still on cold days they don't wanna eat but as long as their spots are black I know they are happy. I don't know if its completely true, black spots equal happiness as I have heard, but for me and my fish it is holding true.
This fish is a good fish for the price but I sorta wish I had spent the money on a little bit flashier fish. When these fish aren't completely happy they look a bit drab.
