GUYS these fish are in no way damaging the ecosystem in my area, 1) it’s too cold for them to survive in regular bodies of water because it’s too cold they will die off when winter hits. 2) the spring is cut off from the main river, these fish were dumped in here by someone with aquarium fish and have been there since for years. Even if they did escape into the main river they will have many other larger fish and predators that could have these 6” firemouth for dinner. There is no way they are hurting the ecosystem at 6” long.
The Only reason these firemouth are able to survive in this spring is because this little spring never goes lower than 70 degrees.
Now tilapia on the other hand are invasive, and should be killed if caught but I haven’t identified the “tilapia looking fish” so why would I just catch it and kill it?
