Thnks for the info...but yes i do know this. The puffer was going to go in my 90 but... the day he came in was also the day i had to rescue 1 6"JD 2 3-4" jd's a 3" concict and a 4" firemouth.... so putting him in there was not an option anymore...so i placed him in the moor tank... ive had the moor since he was very young(like platy small) so this was the safest way to go until...
