Dojo passed last night

Not sure what happened. I did move the angelfish out cause I was reminded dojo's prefer cool water. So I moved it and put in my white clouds and started to lower the temp slowly.
This morning one of the male dojo's was dead. Last night it was fine. Tested the tank and it is fine.(and for you nosey people I am not listing the test I have been keeping fish for over 20 years I know what it is suppose to be.) Must of been stress.

Some moving and redoing and breaking down.

Broke down the 10 gallon moved plants to 20 gallon and my 6 gallon JBJ nano. The only thing I don't like about this tank is it does not photograph well. But in real life is looks great.
The picture up top (cause It wont let me put there where I want to put them) is the 20 gallon as of this morning. The one on the bottom is the JBJ nano.

Moved fish around

Moved the goldfish, dojo's and one BN pleco to the 55. Move the Oscar and Jack Dempsey to the 75.
They all seem fine.

55 has two filters the rena xp3 and a bio wheel 400.
75 has one filter bio wheel 400. I well need to add a second bio wheel.
