So do you know any of their requirements? I live in New Zealand if that helps. Thanks

Hi, so I found this guy out in my water tank can I get some identification and requirements to keep him alive? Thanks.

Some weird results here.. What should I do now?

Haha yes, can I try this experiment without an air pump? And also for the tank, should I just let it sit for 2 weeks and observe? Thanks!

So previously you and another person told me to leave my tap water out to let the CO2 escape, that is just what I did, sorry for the confusion and (probably) misuse of a term. When my tap water comes out it is at 6.0 and the next day (there are bubbles which I assume is the CO2) it is 7.0. I’ve...

Yes, though I am not sure it has changed because I haven’t tested it since. This time though, I have a large bucket to decarbonise(?) it before using the water (water came out at 6.0 and became 7.0 after from what I remember). It is a UV filter so it probably shouldn’t affect the pH. I will do...

Hi, so about a week ago I decided I wanted to have a go at fishkeeping again. Previously I had set up a small planted tank (52l ~ 13gal) but had problems with pH fluctuations, which can be seen in this previous thread. I had left the tank running for a few months and only turned on the light...

So far I have not come across any small herbivorous fish so I am interested if there are any?

So after a WC I saw a stream of bubbles coming from the leaf of my plant, you can’t see in clearly in the video but it certainly is.

Ok, what else should I do in the meantime? I will see if the shop has a CO2 and O2 test kit.

Could it be that the water just takes a long time to outgas the CO2? Because today I tested the control water and it is still at 7.2 However the tank is at 7.8 after I did a WC yesterday.

Ok so I don’t think they do, we use UV sterilisation.

Hmm, I actually don’t know, I will have to check

The water is collected in an external tank in the forest. As it is pumped up to the house it goes through a few different filters and comes out as tap water. I just use my tap water for my fish tank.

I will reduce the dose to 1x a week. Yes the substrate is just Flourite.

I have a piece of driftwood and some plants in the tank, that’s all. Could the filter media be affecting pH? I use filter floss top layer, and then seachem matrix. I only use Flourish Comprehensive Supplement.

So based off the advice of a few members, I have done a test (results below in photos, go into the photos to see the info), and the source of my pH fluctuations (rising steadily) is probably not due to the substrate. I put about half an inch of the substrate in a bucket of water and left it for...

Mystery snails have an average lifespan of 1 year even in good conditions, so having one that lives up to 2 years is really good!

The pH in my tank is now 8.2, should I do a water change or just observe? I am still currently testing if the substrate is affecting the pH like you guys suggested.

Ok so I’m putting the Flourite in today after out gassing the CO2 yesterday, will check pH every day.

I guess that would explain why my water has a pH of 7.0 but gH and kH of 2.

I have a personal/private tank which collects rainwater from a stream.

Does the pH not affect them? I've read that neon tetras, for example, thrive in pH of less than 7, as do most of the fish you have listed. The tank dimensions are 51 length x 30 width x 41 height (in cm).

Ok, thanks. Do you have any recommendations for what fish I can keep?

Well since my pH is so high, I was thinking about keeping high pH fishes instead, like some guppies, otocinclus, and some snails. For the bristlenose I would have to alter the pH while for the guppies etc I would have to increase kH and maybe decrease pH a little bit. Which do you recommend?

I try to keep the light on for 9 hours a day, I use Flourish COmprehensive Supplement 2x a week (dosing 1 ml each time, my tank is 52l), I used to do 50% WC 2x a week, but I was advised to not do water changes during a silent cycle. In regards to the substrate (if I kept it), what could I do to...

Ok so how would I be able to prevent that? There is just a lot of hair algae (I think) on the leaves of the plants and some on the glass, the photo resolution isn't too good so you might not be able to see it in the photo.
