Can I pit these fish in a 29 gallon aquarium?

  • We are currently upgrading MFK. thanks! -neo
Again I'm no expert on water chemistry but IMO stability is more important than chasing a target ph. My tap is 8.2 and I kept a couple gouramis for 3 or 4 years until moving and setting up a different tank when i was young enouch to not know about water testing besides the basic cycle. This is a forum so you'll get a lot of opinions, and there's a lot of experience here, but it's your tank, and your fish.

Thanks! I'll just have to figure out what to do. At least I can still get the platys and bristlenose...

I don't know how my local pet store can care for the fish at that ph though..
 
Well likely they don't worry about the ph, they probably count on the fish being there a short enough time to notice any ill effects. Depends on the store too, my lfs has tanks marked RO for certain fish.

Would this work? If not, there is a reverse osmosis water dispenser at the grocery store. Would that be an option? It's 39 cents a gallon so I'd be able to do that as well
 
I can't currently see the pic of your test results, but it sounds as though your pH is 7.4? If that's correct, you don't have a thing to worry about, at least regarding pH. Virtually any fish you are likely to choose will be fine at that level; some species from more acidic natural environments might be less likely to breed at 7.4 but should be otherwise healthy. Even those species will likely have been captive-bred for many generations and are already better adapted to the more alkaline water than their wild-caught ancestors.

I have water that is usually around pH 7.5 or so. I don't worry much about it, especially when dealing with small species in particular. Platies, tetras, barbs, etc. have natural lifespans too short for long-term chronic effects to show up, assuming that they ever will. Large cichlids, large catfish, etc. live much longer and so if you keep a fish that will live a long time and is also sensitive to higher pH then perhaps a problem might eventually develop.

So, yes, you can buy an RO unit which will produce soft, acidic water, and you can mix this with your hard alkaline water to create a more middle-of-the-road chemistry which is theoretically better for most fish...but IMHO all you are doing is wasting money, creating more work for yourself, and virtually guaranteeing that your tank will experience up and down swings in pH which will...again, IMHO...be far more deleterious to your fish than a stable 7.4 ever would be.

It ain't broke...so trying to fix it is...IMHO...just creating potential problems where none currently exist.

As an aside...I love Oscars. I think they are one of the most underrated fish in the hobby, in terms of beauty, personality and just about any other yardstick. But I don't keep them, because they are one of those long-lived species from low-pH water who may develop HITH erosion issues when kept long-term in hard, high-bacteria-count, nitrate-accumulated aquarium water. The point being that you just have to resist the temptation to keep species that aren't well suited to the conditions you can provide. Luckily, in your case, just about anything you are likely to put into a community of small fish will do just fine in your water...no pH-juggling or RO-ing required.

Thanks! The tap is 7.4 I definitely do not want to breed so that will be great! I'll do a water change because the ph in my tank is higher then my tap.

I read 8.4 originally - 7.4 isn’t much of a concern.
I have a blue (threespot) gourami in 7.4-7.6 with no issues.
I have or have had all of the fish on your list in water like that with no visible effects.

One on left is the my tap water. On the right is my tank water. Left one is around 7.4 and I don't even know what the ph count on the right one is

What level of ph is the one on the right? Lower or higher on the spectrum?

And why is the tank water at this level and not the tap which is the same. I even replaced almost all the water with the tap again but it still changes when the water goes in the tank. Could it be the conditioner I'm using?

Water conditioner should not change the pH of the tank.

Did you leave a sample of your well water in a clean glass container for 24 hour before testing the pH? Sometimes the pH will go up or down depending on your water source.
