I respect your decision to return the regal, the right thing to do. The Koran is going to need more room in time however you are aware of this and he is just a baby at the moment, you should expect that you may have to rehouse him in around a year or so. I also think you may be fine with the butterfly but should keep an open mind. I sometimes think the guys from the uk get a slightly rough time on this forum over SW
, tank sizes, ideas on equipment etc. What people forget is that the UK imperial gallons are around 20% bigger than US gallons, not that this is necessarily the issue in this case. I actually don't think anyone was trying to be funny here though, just imparting knowledge he felt would be helpful.
