so i think i figured it out, awhile ago Ares took a chunk out of his tail, i couldnt figure out why, now i got it, its when i do a clean and water change. it obviously freaks him out and he then bites his tail
, i did a big water change today as i realised that something was abit wrong, turned out my filter had quit on me, dont know from when but i shuffled around and now have another filter in there. figured out that something was up when i was losing like a shrimp a day the last 2 days. anyway i'll be keeping his water super clean for now and keeping an eye on him. he obviously doesnt like major things happening in the tank,i had to replant some cuttings that floated out the gravel. unfortunately this is a necessary thing and i suppose i could cut it down to once every 2 weeks with the filter but i cant leave it longer than that. i like to do weekly water changes and gravel vacs on all my tanks but if Ares is getting upset i dont have much of a choice. just glad i figured it out.
