Hi all, Im fairly new to fishkeeping and wondered if anyone could help with this:-)

I have notice recently that my tank is developing small green spots on the inside of the glass, could this be Algae?

My tank is a 48" x 12" x 15" communal tank with plastic and silk plants... (I used to have real plants but they all started to go brown and fall apart so I removed them all)

I have been set up for about 2 months now

I have it stocked with

3 aquatic frogs
5 zebras
2 harlequin tetras
1 male siamese fighter fish
2 female fighter fish
5 diamond tetras
2 catfish
1 red tailed black shark
3 orange platys

If It is algae would I be better buying an algae treatment or adding an algae eating fish... if adding a fish what would anyone recommend re: mixing with the fish listed

Thanks

Green spot algae can only be removed by scraping it from the glass. A good time to do this is during a water change /gravel vac. Why add chemicals to the tank? Also, there really isn't a fish that eats this type of algae effectively.

why not scrub it off by hand.

2 catfish can mean anything, so if possible a name could be helpful.

3 bettas together....

ottos might be right, but i am not sure how they will wrk out with RTBS

There is often a lot of talk about algae removal by chemicals in a fish tank here in FP. It will work and remove all the algae BUT and and a very big BUT it actually poisons the algae to kill/remove it then can become toxic and very likely kill many of the fish in the tank. The best way to remove it is to use a glass cleaning pad (sorry do not know UK name) I have been using this type of pad for many years it will not scratch the glass at all. It is best done at the water change time. If it is a huge problem you will have to look into what is causing it.

Have a look in [link=My Profile] http://www.fishprofiles.com/forums/member.aspx?id=1935[/link] for my tank info

Near enough is not good enough, therefore good enough is not near enough, and only your best will do.
I VOTE DO YOU if not WHY NOT?

Thanks everyone for your suggestions, I will try and remove it with my next water change...

The 3 bettas, we were told in the shop that it was better to have 2 females to 1 male

The catfish are Corydoras aeneus

Thanks all

Cories, IMO are not the best algae eaters. I've had the green algae in my tanks and am a huge fan of ottos. My rubbernosed pleco won't even touch it. Please correct me If I'm wrong about the cories, I've just never seen them eat algae
