Funny that I had to do a look up on your gibbiceps.. could not for my fish memory recall this fish at all.. SO once I did find out, SHOCK!! Ok not really but I was surprised.. A common Sailfin Pleco as we call them in the USA.. So now I know...

ON the name, it is no wonder that this did not sound farmiliar:
The Sailfin Pleco was first described in 1854 by Kner as Ancistrus gibbiceps. It was renamed Pterygoplichthys gibbiceps in 1980.
~ The scientific name Glyptoperichthys gibbiceps became valid in 2003. (taken from the text below)
As yours is like 7 in. now, just wait...He wil get bigger fast.. With Oscars, make him a place on the bottom that he can just get into.. Sometimes Oscars get nosey and they might pic on him.. He will swim away and hide or defend him self with his fins.. Some fish do eat thier eyes out.. Mostly African cichlids do this... Mine got to ONE foot+ American size... As I was feeding him in a smaller tank, I traded him in.. So be aware of HOW big they do get.. I Saw a female that was ALMOST 2ft long in a inside pond!! Man, she was huge!! Her head was just enormouse for a Pleco..
http://www.wetpetz.com/gibbiceps.htmlNOW on your tank.. Your 250 lt tank is a little over a 66 US gal tank here.. So just make sure that you have just the two oscars and that Pleco.. At adult this tank is going to be full.... Also you are going to have to feed that pleco as a new tank does not have a good sorcse of Algae for a few weeks.. Mostly what wil show up is that Red/brownish algae that most plecos dont' like.. PAY ATTENTION TO THE DIET of the pleco in that Profile and what you can feed him to help him out.. this is important as some do starve as ppl dont' know that algae is NOT enough for them ONLY...They will feed off the top like they say.. MINE did this as he liked the floating pellets too..
As you have enough tanks, I guess you know about cycling and such.. I Like the sound of your gravel color.. Black and gold.. Sounds like a neat Idea for a substrate.. GET us some pics when you can ..
