I lost 8 cichlids last night all of which were covered in like a while slime the next morning, I have no idea whats wrong in the tank. One of the cichlids had his insides turned out and it didnt look like an injury or attack. I lost my breeding femal Auratus who was 4 years old. Im at a huge lose Please anyone i need any advice. Oh and i still have about 7 still in the tank what should i do to save them??

What size is your tank? Water stats? Might be better to post this in fish emergencies.

Also tell us what all the fish in the tank are. There could be an attacker or it could be a disease, or your water conditions.
