algae on plant leaves
Does anyone know about this algae growing on my plant leaves?

I had some green algae a couple of weeks ago so cut back on light time and have reduced feeding and have not had any back, but now this one.

I have only 2 male guppies in the tank as it has been cycling but was planning on getting a couple more fish this weekend, could corys eat this algae?

I'm no expert with algae eaters but I don't think cories would eat it off plants. They tend to be bottom dwellers. A true siamese algae eater would do the job I think because they like to rest on plants and leaves, and are known to be excellent algae eaters.

It looks like staghorn or BBA. Might be a string algae but looks a little too compact and clustered. If you have the room, Florida flag fish and rose barbs are supposed to be good fish for controlling algae.

It is a shortage that causes these though so if you can list your parameters, KH, GH, Nitrates and phosphates and also tell us what you dose as well as your lighting we should be able to help you get a hold on the cause and get rid of it.

Also, it is amazing how effective Flourish Excel is to get rid of this stuff. You can squirt it directly on the algae at the normal dose and it is dead in 3 days. Regular dosing helps to control most algae also short of green spot algae.

Aslo can't forget otos but with a newer tank i can not recommend them because I have never been able to keep them alive in anything less than a 6 month established tank.

I've seen cories eat algae off plants, but usually only if it's lower to the substrate, like javamoss patches. I'd recommend getting amano or cherry shrimp or some oto cats. Plecos are also good, but tend to get pretty large.

i purchased a flying fox to deal with this and he does well ,mollies will only eat this if very hungry

Amano shrimp also eat algae very well, but as fish4all said, discovering the underlying problem is necessary.

Similar problems
I'm having a similar problem. After a recent nasty outbreak of Cyanobacteria I cleared up the tank and now have other algae starting to grow on my plants. I can't give the test readings because I just changed the water but I have a 29 gal aquarium with a Current 65w compact florescent full spectrum bulb. I have two powerheads and a marineland filter. I use 3 cc's of flourish excel and 12 cc's of flourish daily and only feed a pinch of food once daily 6 days a week. I run the light for 9 hours and have about 10 fish including a chinese algae eater. Any suggestions would be great, because the tank is b-e-a-utiful when it is clean and running well. thanks

Do the leaves on your plants exhibit the black stress areas along the leaf perimeter as indicated in the first photograph?

Yes it does, what does it mean?
