Fish moving advice

So it looks like I may be doing some aquarium rearranging soon. The main reason I am doing this is for my featherfin catfish. He is in a 45 gallon aquarium but I am considering putting him in a 40 breeder. The reason for doing this is that he is the longest fish I have and the 40 breeder is the widest tank I have as it is 5 3/8 in. wider. It is 1/4 in. shorter in length and 7 3/4 in. shorter in height than the 45 gallon. He has no problem turning in the 45 gallon or anything like that but I am just wanting to give him the best environment. What would he like better, wider or taller?

Wider!

That's what I was thinking Finley, thanks! He and the pictus should be interesting.

Since its only a 40b then I think,but could be wrong that the featherfin will bully the pictus cat!The featherfin really needs atleast a 75g or bigger,but if you ain't got the room for one then I guess you put it in the best tank for it!

I also have a 55 where I can put him, and it is obviously longer than both but has has the same width as the 45.

The 55g would be the best tank for him then!

Well I will look over my stock and plot a course of action. lol

How do you think a featherfin would do with rainbowfish? If he goes to the 55 and they won't work they will go to his old home.

Just keep an eye on them!
