my arowana has drop eye on his right eye but its not caused by the usual reasons. when he was only 3 inches long my blue mawali attacked him. now he is two foot long he has developed a slight curve in his back as if he is compensating for the drop eye. i just wondered if anyone else has experienced this. thanks my tank is 6x2x2 running two fluval 305s 15% weekly water change tank also planted. he lives with a african bush fish pleco and blue mawali who he hasnt got his own back on yet.
