HI all. My crayfish is an 5" electric blue cray living in a 10 gallon tank. I got him when he was just a little below 2". The thing is he never witnessed me cleaning the tank while he was inside so he got terrified. Before the cleaning our relationship was good..he would come to me every time I open the lights and sit in front of tank. I usually throw him an algae waffle and he would grab it and go back to his den. However, a week or two ago I noticed when I just open the lights n sit n watch him he would scrabble over to look at me for 30 secs to see if I drop him anything, if nothing he would just scrabble back to his den for a minute and scrabble back out n see if there is food. He did this behaviour until he sees food on his third attempt. Normally he would grab the food n scrabble back, but this time he stayed with me a while and did the scrabbling back and forth until I drop another one...he would keep eating while he walks and grab the other one with his pinchers or just guard them with his pinchers. My guppies learned the waffles r "his" food so won't go near it when he is around. However, this behaviour changed after I decided to clean the tank. Like I mentioned, he never witness me clean the tank so he got scared. He was so scared he squirmed back to his den and broke the wall so to top collapsed on him. I had to fix it a few times and did moderations to make sure it is safe. Anyway, been a day or two now and his relationship with me was bad. Maybe I got him ed and now he thinks I am his enemy. What can I do? I read this article:https://www.independent.co.uk/news/...can-feel-anxiety-scientists-show-9532781.html and they said crays could get stressed too. Is there a way I could rekindle my friendship with him?
