New giant guppies sick

[rmjohnston92]

Apologies if there's a similar post or if I'm doing this incorrectly.

I recently purchased some new giant sized? female guppies and  one is sitting on the substrate fins clamped and the other is at the surface with the top fin clamped. They're eating and will only move if another fish bothers them. I had .25 ammonia two days ago and performed  water changes each day. I'm curious if it's ammonia burn, stress, or some infection. I'm hoping it's just ammonia burn. But I don't want to throw meds at them and stress them more if it's not needed.

 

PH- 7.6

Ammonia-0

nitrites-0

nitrates-5

temp-78

kh-40ppm

gh-30ppm 

gh/kh with api test strips

I think it's a combination of the small amount of the new digs, the small amount of ammonia, and mainly, the fact that you have soft water. Livebearers really want a higher GH and KH. You can supplement GH/KH with Crushed coral, Seachem Equilibrium (or replenish), and Wonder shell.

Just retested the water. ammonia-0, nitrite-0, nitrate-0. Now they're all sitting at the top breathing rapidly.

Do you have an airstone?

What I would do is daily water changes and add a double dose of prime to help detoxify any ammonia and I would add an extra air stone as there hanging near the surface and some crushed coral to help raise your kH and GH
