The tig stopped eating for like 3 weeks and I wasn't sure why, I moved the lung out to the other tank thinking maybe the AUL was bothering him (he was, ate about an inch of my tig's bottom streamer lol). But the tig didn't start eating even after that for like a week and then started eating again after sometime. I realized recently as to why:
The only fish in my stock capable of such doing such damage is my ray... I'm glad that the tig pulled through and is eating like a champ again. I'll have to considering separating these two soon.
