I finally got my Dat to eat a earthworm,then awhile later he is swiming with a clamped fin and scratching(looks to be ick)this fish was sold to me as a Silver Dat,but i was told it grew up in freshwater so i dont think thats the problem.Do i need to take the same precautions(water change,extra salt,and raise the temp??)Please any help is really appreciated!!
