It sounds like it might be blue green algae. Look it up on google for pics so you can confirm if it is actually that. blue green algae is caused by poor maintenance and often by over feeding bloodworms. It also is not algae it is a bacteria. sorry cant remeber the name. look it up for more info. How long do you keep your light on.

As for your stock it is fairly poor IMO a 20 gallon is too small for rainbows and they should be kept in schools of six or more. As for the red eye tetra it also needs to be in a school of six or more same with the black skirts and the cory cats all schools of six plus.

as for the cats that should be cleaning the tank IMO/E they are not the greatest algae eaters what type of pleco do you have they are great algae eaters but if it is a common pleco it needs a tank of 100 gallons plus.

this may sound overwelming but we are here to help.

What type of algae?

I have to point out how wrong your stock list is. Rainbows, cories, red eyes, black skirts and kuhlis are all schooling fish and need schools of their own kind of 6 or more. The rainbow and probably the pleco need larger tanks.

Blue green slime and smear algea and I know they both get big but the pleco is only 3 1/2 inches I know to move it when its bigger and the rainbow was originally in a thirty but the temp of it dripped and some stuff went wrong and him and the kikuhli loach were sluggish so I put them in my twenty gallon the lived and I've tried movie them into the thirty gallon twice both time they started floating at the top and acting sluggish so I would just net them and put em back in my twenty not floating them in a bag or anything and they were fine 0.o I know wierd but I don't have another choice but what do you think about the algae??

Yeah that's how I figured it out also it's like on one of the ornaments it's like a super green sheet going over this mini bush looking thing.... Almost like I see all the points of it but it's blanketed in algae
