So I have a Redtail cat at around 13" ive had since he was 2 ", I recently threw a nigerian african lungfish (around 18" in)....they dont like each other.Since I threw in the WALF my redtail (which wants nothing to do with the fish) has been attacked along with my brycon dentex (no serius damage though already healed) but im worried the hostility will only get worse with time. Ive never actually noticed the confrontations but im only assuming its him since before he arrived my clown knife,gar,redcat,and brycon never had a problem with each other. Looking for advice.I dont need a lecture on tank size for the florida spotted gar and red cat im fully aware and wont entertain it ,they are all content in the 210 they are in as of now and I understand they will outgrow it. Im simply looking for advice whether the lungfish will have to go. Im a big fan of the fish but ive had the gar and knife for 2 years and the cat around some time as well and wouldnt want to see them seriously damaged.
