These are 4 young normal eyed bristlenoses. No ornate finnage, sorry. These are youngsters that were raised in my 10 gallon tanks and then transferred into the 55 gallon. 

Bristlenoses do a great job in keeping most algae off your glass. Don't expect them to eat all algae (I'm a bit picky myself :)  )

Fish are probably 1-1 1 /2 inches long, probably 4-6 months old, unsexed
