I did a 30% water change on my 90 gallon oscar tank sunday. This moring thre was 20+ white worms foalting on the surface. Most were dead shells but when I netted them three were wiggling and they had small black eyes. They looked liked mosquitio larva. Any ideas were they come from or what they are. Should I treat my tank for parasities?
Thanks,
