He may be slightly stunted as I said I bought him from local ads and the guys tank wasn't exactly big mostly his reason for sale , we'll see what happens once he's in my main tank he should stretch out a little thenhe does look short and stumpy atm though your right rotary
Good save, look like he has plenty of room to swim. I wouldnt mind paying £10 for a 6"-7" albino sailfin.
