Yes, LDA33/L142 is also caller a snowball pleco...... the second fish is (in my eyes anyways) a L262 not a L004, L028, L073 (AKA Angelicus pleco). There are way to many spots on the fish in question to be the Angelicus pleco...... I have both the L004's and L262 along with others that are very similar looking as well (L136 and L404)+1 first is snowball and 2nd looks like angelicus.
Plecs are very difficult to ID for sure...... Vamps (L240, L007, ect) have a backwards facing "horn" on the head plus a frilly skin flap (sorry for the life of me I can't think of the correct name for this) on the front lip.L142 Looks like a good prospect, the mouth in the reflection lead me to say L240. Body definitely L142, the mouth is throwing me off...but hey, I'm a as L14 guy...lol
