Whats this growing?
 
Hi I was wondering if anybody knows what this is growing in my tank..Im assuming its some type of Algae, is it harmfull for the fish and should I be trying to get rid of it? This is my 20 gal tank that houses 1 pleco and 2 moores. Oh and why dosnt the pleco eat it? I give him the algae disks once in a while...any feedback will be much appreciated!

It is BBA, Black brush Algae. Not harmful to the fish but can be a pain to get rid of. From the looks of it you don't have live plants so the best combat would be to shorten the time your lights are on. Doing regular water changes will help to prevent nutrient buildup which can help prevent algae.

The BN won't eat it. The only fish I know of that will touch it are SAE and Rosey Barbs but I would not recommend getting them with your pleco and Moores as both are fin nippers.

I've never seen SAE's being fin nippers however the combo is still not recommended especially when the SAE's need plenty of room to swim around and these are tropical species not to be mixed with coldwater.

Another is American flagfish (Jordanella floridae). It's a tropical fish and unfortunately shouldn't be mixed with goldfish considering their nasty temperament.

Which one of these fish? Image for CAE (Chinese Algae Eater) is not included but you can look it up on google. The mouth structure and nature of SAE does not suggest exact mouth-sucking behavior. These are very peaceful fish, though confused with other species, it will never try to suck a fish out of curiosity or hunger unless it isvery seriously underfed which all too often does happen among plecos and otocinclus catfish.

They don't. What you pointed is a false Siamese Algae Eater. The mouth structure is very different to the true SAE. They don't get aggressive towards other species but I never have known them to really suck slime coat. Inadequate food diet would trigger this.

I decided to move this thread here.

Well there in lies the problem. All too often LFS recieve fish that look like SAE and it may be a Flying fox or something else and the next thing you know you have fins missing from fish when you thought you had a non-aggressive fish.

The FFF, Barbs and true SAE will eat it and a red tail shark is supposed to although I have never had this confirmed. Be aware though that most of the fish will only eat the younger shoots and if it gets too bad you willhave to do some manual removal.

Something to try if you want to really get rid of it is to get some Flourish Excel. I have found it kills almost every algae short of green spot and won't affect your fish if dosed properly.

Do you have any live plants in the tank or are they all fake? If all fake, don't try the Excel as it could stay in the tank and build up over time.
