Over the weekend, I got a new fish to clean up the hair algae in my frag tank. It is a blotched rabbit fish. They grow quite big so I need to get rid of it eventually. They have poisonous spines so do not let inexperienced children by the tank if it is open. I decided to take the risk of putting it in an open tank, even though they are jumpers. I acclimated him to the tank and put him in. He started to act weird, swimming in place. I realized that my flow was very strong, and he couldn't swim. Neither my powerhead or pump are adjustable, so I pointed the pump down to keep detritus from sticking and the fish gets less flow. The powerhead is pretty strong so I pointed it a little downward. After I did that, in a matter of a few minutes, he was swimming about the tank normally. I was very relieved. He is incredibly peaceful and a good fish to clean up algae, as they are herbivores. They are not like damsels, darting around the tank, so you do not need to be concerned if it isn't swimming well. What is your favorite fish? Comment below.
