An 180g is barely big enough to even stunt the growth of a pacu - they'll break the tank, maybe not now, but they definetly will, and probably within the next 6 months. Try something like 1000+ gallons, and even that would be a little overstocked with the fish you have now.

What kind of algae eater can I put in the tank (without getting eaten)?
You can add
nothing living to the tank, so that means no algae eater. And no fish should be bought for the soul purpose of cleaning your tank - that's your job. So, instead of an algae eater, what you will need to clean you tank is:
- A gravel vacum - use this to do 50% weekly water changes, while siphoning fish waste and uneaten food from the bottom of the tank. Also, contrary to poular belief, nothing will eat fish waste.
- An algae cleaner- this will be either a sponge, a sponge atached to a handle, or a magnet type thing. Use this to clean algae off the tank walls as needed/wanted (fish don't care if there's algae in the tank, and many will apreciate it). Also, no algae eater will keep the tank cleaner than you can, and many stop eating algae at a certain age and need suplemental food.

Pacu can grow up to 2 feet and are very active - why they are/will be capable of breaking your tank, and need a huge (1000+ gallon) tank. They also live forever whn you keep them in a proper setup - debra mark (other forum memeber) had a black pacu that lived to be 28 years old, and was kept for the most part in huge tanks, the largest being over 3000 gallons.
The oscar still gets big, but not as big a the pacu, it will grow to be over a foot in length. And, tankfully for you, and 180g is more than big enough for an oscar, actually it's big enough for a group of 2-3 of them.
