Here’s the tank btw, it’s a 20 gallon long.The pH is 5.5

Gotcha, man i wish i could find some that cheap

Yeah, neat fish, but not worth the gamble at wallet shredder pricing for me.

 

[fanning88]

Gotcha, is it ok if i get 3 instead of 5?

I keep a group of 7 in a 55 gallon. They do just fine with my tap water. They do occasionally chase each other but there is no nipped fins or anything.

 

[PissBabyTheFourth]

Hm. I’ve also found A. Iniridae for sale, but I’m not sure if them or the dicrossus would be more interesting. What do you guys think?

I think you might be able to guess my answer.

Just a question, because I think it's due to the lighting in the picture: There's only biofilm on the twigs, not cyanobacteria, yes?

They do just fine with my tap water.

You emphasise that in the few posts you've written until now - Care to share your water parameters? Because it's always a difference if one's talking about simple holding conditions or biotope/breeding tank conditions.
The term biotope is often used here on the board to denote making the effort of recrearing softwater habitat conditions.

The pH is about 5.5, and I believe it’s just algae and biofilm. I’ve never really dealt with cyanobacteria or any kind of algae so I’m not completely sure.

The question about the water parameters was for @fanning88 , not directed at you.

Ok, so it's just biofilm in a greenish light. Just wanted to make sure.

Oh no the stuff on the branches is green, i thought it was just algae

Can you take some better pictures? If that turns out to be cyanobacteria you might have a problem to solve before adding fish.

 

[PissBabyTheFourth]

Gotcha, I’ll send some pictures as soon as I’m home

Take your time, I'm only going to be back online late tonight.

Yeah, unfortunately thats cyanobacteria. I've just finished a fight with it lasting a while. It's stubbornly resilient and shockingly fast-growing.

 

[PissBabyTheFourth]

oh man, how do i get rid of it?

 

[Bramgroet]

If you don’t have plants in the tank you can put the light out for a long time I don’t now how long. Someone else will probably know how long.

 

[MacZ]

There is no general course of action. Blackouts and more competition from plants have helped me. But I had a fraction of the amounts you have there.

Ok, first things first:
Full water parameters? (GH, KH, NH3, pH)
Composition of your sourcewater?
Maintenance schedule?
Light schedule?
Position in the room relative to the window?

Hi all,

Yeah, unfortunately thats cyanobacteria.

I don't think it is cyanobacteria (in fact I'm pretty sure it isn't), it is the wrong colour but both colour and filaments look much more like a <"Green Algae (Chlorobionta)">.

It is only really green algae that are "grass green", because only they, and all the higher plants, possess chlorophylls a and b.

Basically it would be a darker blue green and a lot more slimy if it was cyanobacteria. Image from <"https://aquariumscience.org/index.php/16-4-blue-green-algae/">

You could also try <"sniffing a bit">.

I basically agree - but it is a bad kind of green algae - no clue if it is bad health wise for fishes but it grows when things are way out of whack. This is of course a non-scientific observation that i get that sort of algae when i goof and something is dying - like when i cut all the roots off my frogbit and it goes south removing the offending thing (as oppose to black outs) usually solves the issue. For cyano - i've had it form for different reasons - usually from nitrogen release of anarobic bacteria (I think) or something like that and a bit of current to blow the nitrogen away usually solves the problem. I had a tank with the stuff once (an old tank setup for over a year) and it was growing everywhere and quit deep - and then suddenly one day it stopped and a week later it was all gone. Mysteries are great but still concerning.

Hi all,

I don't know. I don't tend to get much green algae, all the bottoms of my tanks are dark and gloomy places with just <"Bolbitis heudelotii"> and moss and I always have a fairly complete <"layer of floating plants"> and snails etc.

If I have a brighter (more intense) light I just have more plants, so hopefully by the time it reaches substrate levels there are very few photons left.

There is a tint of green in the pictures that makes me think it's both cyanos and green algae. Which would surprise me as I rarely see them both.
