Actually, the identification of trichos is a very difficult task and the length of spines is only one characteristic that does not necessarily make it not a pedro. It could be a peruvianus, which are known to be more blue and are also active. It could also be a bridgesii. I'd check out www.troutsnotes.com
. There you can find an email address for some tricho experts and if you send them a link to a pic then they may be able to help, but also part of determining it's species/strain is how it flowers, so you may have to wait to get a true identification. In other words, you probably have some sort of trich, but it may not be pedro(still can be active).
