Hi, I want to get some bristlenose catfish for my 90gal to get rid of some green "hair?" algae I have growing. Question is, how many should I get and will they eat my plants? If they will then what can I get instead to do the job but not eat the plants. If i catch them eating the plants they are going back to the LFS!

Thanks!

You have to feed your bristlenose veggies to prevent them from eating the plants. Some fish eat specific types of algae. Seems yours is filamentous green algae.
Give Amano shrimps a try. They will often relish hair algae. I have read a few sites stating rosy barbs as the solution to eliminating hair algae.:shock2:

I have 4 Amano Shrimp in there already and I have no clue where they are. They are hiding in the plants I guess. Also, they don't seem to ever get the algae off of the glass. How many shrimp should i have for a 90gal?

20 should be fine. You have to be aware with the fish you are introducing. Their exoskeleton tend to soften making them quite vulnerable to being eaten.
Angelfish tend to eat shrimps so you will be given a choice: angelfish or Amano shrimps.

Well you know I'm getting discus. So the question is, do I care if they eat the shrimp?

For this case, unfortunately, they will.:blueworry: So I guess you might have to settle with a BN.
But if you can provide thickets of plants aside from those you have currently, the shrimps may survive.

Ive looked in the tank thoroughly and only once have I spotted a shrimp. The plants are becoming think so maybe they will be ok. However, if I get some bristlenose, how many for a 90g?

One or a pair is enough. Pls take note you'll be doing more water changes as BNs tend to poop a lot.

BN's do not eat hair algae.

Amano shrimps do not eat algae on glass. If the algae on the glass can easil be rubbed and not scraped off with a blade, then BN's, ottos, even Gold nugget plecos should be fine.

Black Mollies are good algea eaters..but It is important to NOT FEED THEM then they are not so eager to eat algea.
Otocinclus sp. are also good algea eaters and Amano shrimps.
The Amano shrimps i also have in my 75g tank..i had 10 but i think half of them are eaten but they will survive if they have hidding spots.

The thing is it's hard NOT to feed mollies, if you have other fish in the tank. They are grazers so will eat what they can get to.
I thought the tank was in cycling modus :?:

I hate it when i have to say this, because i love plecos.

I think the best pleco for your tank is a sponge on a stick. sad but true :( feel free to get some anyway though! you wont be disapointed!

Hi Funk: Good to see you!

Back to topic.

Have you considered Siamese Algae Eaters.

I had a serious algae problem: algae bloom, algae on walls, hair algae on rocks, wood, plants etc.

I used lighting control and filtration but also procured seven SAE's.

The SAE's were very small three months ago but are now approximately 3".

They are very nice looking fish, add activity to the tank and really help to control the algae.

Good to see you to jones.

Siamese Algae eaters is a good idea, make sure not to get chinese algae eaters though. They get twice as big, 8 or 10ish inches. the Siamese get like 4 or 5.

what i was going to say! and bn will eat your plants, i have heard some people say they wont but from first hand experience they do! even if they are well fed they like a nibble on soft leaved plants, java fern, anubias seem to be avoided by most if not all fish

I'm thinking that SAE's will not go so well with Discus once I get the tank settled since they are fast movers and would scare the discus....I would like some plecos so I will start researching them.

Yes:

Not only are they "fast movers" but they also do a "ton of running, romping and playing" with themselves as well as with my Yoyo loaches and Cories.

First, BN don't eat it per say although they will munch at it. I have staghorn on my anubias and they rasp a little at it but don't control it by any means. Black mollies would be a better choice and SAE even a better one. As for not feedng them, don't feed the tank once or twice a week if needed to get the fish to focus on the algae. Rosey and Golden bards are "supposed" to eat it like spaghetti.

Now the issue is really what is causing the algae. You said the plants are massive now. This says there is likely a deficiency of one or many nutrients. Let's see if we can find the cause so this stuff is manageable or goes away completely. Also, what is your lighting and watts?

What and how much are you dosing? Any CO2? I know my tanks have BBA and staghorn because I have low and unstable levels of CO2. The one that has the BBA is dosed according to EI, the other is now a non-CO2 tanks and the staghorn is likely because of too much of something and because of no CO2 which I am going to augment with Excel when I can get some.
