Hey guys so I was thinking about getting a Midevil and growing it out in a 40b. My lfs has some around 2in. If I keep him in good condition water and he is fed regularly, how long would you say I should be able to keep him in the 40 before moving to a bigger tank?
 
about a year maximum, with clean water 8-9 inch from 0 inch fry is about right for a year old ime.

will be very tight at that stage, you will then need a 120g imo.

at 8 inch it will have 4.5x fish length sideways and 2x width ways, equivalent to a 12 inch Oscar in a 4.5ft x 2ft.

as duanes says most wouldn't consider this a good size for an 8 inch fish but if you have a definite upgrade planned then imo a year is doable and its probably better in the hands of an mfk member than a random fish keeper with no clue!-)
 
I really can not say how long you can keep him in there. I see someone said 1 year. I believe it could very well be 2 years. Also if it is just that 1 fish he also is not going to have stunted growth if circumstances causes him to be housed there longer than expected.
 
I wouldn't keep him in there for very long. I'd say 6 months at most. I've seen some midevils grow really fast.

My midevils in a 40g maybe about a dozen in there ( I used to breed them) grew very quickly. When they got to 4 inches I would put them in a 200 gallon tank and sell them. They grow quick with frequent water changes and a healthy diet. I love looking at the midevils some morph colors very nicely. I had a guy who was all black and had a orange fohawk lol
