Hey everyone.... so my sister had a freak accident with her 10gallon fish tank (a friend who was watching it accidentally knocked a bottle of flake food into her tank.... ammonia levels had soared by the time my sis got home and was able to clean it) and only one male fancy guppy survived. It is a month later and the one guppy is doing fine and water params are back to normal. My sister was wondering though if she had to buy fancy guppies again or if there was anything else she could put in there with him instead. She said she doesnt want him to be lonely (knowing they are schooling fish), but at the same time, she was curious if any other fish could live in there with him. I believe she originally had 7 male fancy guppies in there, and the runt of the pack was the only one that survived... ironic. Let me know if you guys have any suggestions for her! Thanks!
