My tank is just under 900 litres and looking for a plec within the same sort of size range of the other two. Is the galaxy plec also a vampire plec? I get confused with all the l numbers generally speaking the Plecos I have don’t seem to mind each other unless it’s over a piece of cucumberHow big are they? Hard to say but I think the L128 is a juvenile male. Can't help with the Rusty Pleco.
How big are you looking for? Blue Phantoms get 6-7" and Rusty Plecos get to about 11". In that range I would suggest a Galaxy Pleco (L007, L240). If your tank is big enough, a Gold Nugget gets to about 10" but can be territorial or a Royal Pleco (L191) but they get to about 16".
I have a 4" L128 and recently got a 2.5" L007.
Decided on a golden Nugget pleco, got him round about an hour ago and all of them are on some lettuce enjoying each other’s companyYes, the Galaxy Pleco is also called a Vampire Pleco. Mine is slow to sense food in the water but once he does, he's not shy eating.
I have 2 tanks with 2 plecos and I have to put 2 cucumbers in each so they don't fight. Otherwise, they get along.
