I know frontosa are african but posting here as this is where I usually post and I'm panicing a bit...
about 3 weeks ago one of my frontosa went missing, I searched the tank removing all decor but absolutely no sign of her. I even searched down the back of the tank. I just presumed died and eaten. However tonight I have gone to clean out the filters and found her inside the juwel internal filter! she is a bit worse for wear with a few abrasions and part of her dorsal fin and tail missing and quite thin
Although she is pale I added her straight back with the others and watched she was accepted and her colour returned. Being the alpha female there was a bit of mouthing till the alpha male saw she was back and put everyone back in order. I have got her to eat buy dropping food right in front of her and she actually came upto my hand for it. I dont know whether to set up the hospital tank or leave her in the main tank I am just worried that moving her will cause added stress!
I have also put this in the emergancy section
