yeah my filtration is great. i just have a single emperor 400 handling that whole 70g. well i found out what it was. i caught him hanging out so i put a light directly infront of him. he has a slight case of ich. i ran to petsmart and grabbed some Rid*Ich. i added the proper dossage and raised the temp to 86. he seems to be doing better. his tailfin is straight white and he rubbed his top fin off. i dont really mind the fins and stuff cuz i know they'll grow back. i just dont want him to die. but i just did the second treatment about 20 mins ago. Once i run out of rid ich im gonna try some aquarium salt since i heard it was better. any input would be helpful. thanks guys and hopefully he makes it through
