hi, not sure if i should post this in here or on the planted section but here goes. i have 3 lovely little pitbull plecos who are great but they have destoyed all my amzon swords by stripping them away to nothing. i had 6 established swords and 3 days after introducing the pitbulls they have been eaten to practically nothing. now i didnt think they were suposed to eat plants but its definately them. is there anything i can do to stop them in future or is it just a case of finding plants they dont eat?
