ya i use to have some synspilums that i started growing out at around 3" and they were about 7.5" within 3 to 4 months. wish my umbees grew that fast. i heard umbees grow real fast but i havent seen that really happen especially with feeding them 3 times a day and doing 3 to 4 large water changes a week. oh well. great looking syns. you have there though.
