Is 7.4-7.6 too high a pH for kuhlI loaches? The articles I've read recommend a pH range of 6-7 but I've also read that fish will adapt to most pH levels , given that they don't experience giant swings. I've never messed with the pH of my tank so I'd love some guidance!
Most PH recommendations are for wild caught to mimic natural habitats and to improve breeding habits, with some exceptions, like Discus (they need very soft, pristine water conditions all the time) and saltwater fish. The majority of fish in fish stores are tank born and bred, usually in neutral to slightly alkaline water (7.0 and greater).
Ask the store what their PH is and as long as it is less than .5 difference from yours, then traditional acclimation is fine (float bag, gradually replace store water with tank water, net fish into tank). If it is greater than .5 difference or you are transferring sensitive fish then you may consider drip acclimating instead to reduce the shock on the fish.
The only problem is that kuhlI loaches in this country for sale are wild caught not tank bred. Which is something I just recently learned while trying to find some. Apparently they are not that easy to breed on a large scale and so cheap to buy the wild ones even with them being imported Alison
Yes, its not just the water. But also a lack of knowledge. KuhlI loaches are quite secretive about breeding habits.
even when it happens in a tank, breeders frequently don't realize it has happened!
even more complications are caused by the fact that a variety of loaches are all named kuhli, though they are not the same type.
Ive had them for years with zero health issues in a 7.5
