Lesson Learned...I had him in a 150Gal tank, but had to put him in a 30 GaL
Quarantine tank. A recently added to the tank a large sailfin tang who began picking on him and he become very shy and hid all the time (lasted for 3 weeks). So I was planning on moving him to another 110 gallon tank in my office, in the meantime I put him in the same Quarantine tank he was in when you arrived.
This time he was in the time a week or so and this morning managed to find a very small space for a very big fish to jump out. I was completely dumb founded to find him on the floor... Small space very big Fish and he still got out.
Space is between the overhanging filter and lid knock out for filter.
He was a perfect and healthy fish, completely my fault. Just hope others learn from my mistake. YOU NEED A TIGHT FITTING LID. take no chances....
