2 new ADFs floating and climbing out of water

[froglett]

I got fed up trying to feed the frogs with platies in the tank, so I've moved the platies to another tank and bought 2 new frogs.
I now have 5 ADF in uk15 gallon.

My other 3 frogs seem happier since I took the platies out earlier this evening and put the new frogs in.
They used to hide a lot, but now they've been exploring the tank more and sitting on the plastic plants for longer.
I also didn't have to wiggle food in their face to get them to eat before the fish did. They found their own food and ate a relaxed meal of brine shrimp.

Im a bit concerned about the new additions though. I didn't see them eat. One has been floating with arms and legs spread around the water surface for hours, occasionally stopping to rest on a plant. Looking relaxed but very different to the original frogs who never did that (maybe because of the fish?)
The other new frog has been doing this too, but then climbed out on top of the filter. I lowered the water level in the tank but she's still got ontop again and has been there ages. The gaps in the lid are already covered but im worried she'll dry out.
I've been dripping water on her from the tank every so often to keep her moist.
Is this normal? Neither new frog looks Ill and they are bigger and probably older than the others.

I think the 2 new ones are girls. My old ones are 2 boys I think, and possibly one girl.
The old frogs look happy and I've just tested for ammonia and it was zero.

The past couple days one of the old boys was hiding at the top of a plant with his nose sticking out of the water and he wasn't eating as far as I could tell. But he's acting fine now the platies have been moved.

The new frogs were in a tank in the shop with newts. I thought they weren't compatible?

I'd appreciate your thoughts.

ETA. Apologies for the edits. Im trying to type on my phone and predictive text is a nightmare

Oh no! Just checked on the floating one and he was floating upside down hardly moving on the surface.

The other one was still on the filters so I gently pushed him off and he immediate started floating on his back too!

They're still barelybarely alive but im putting them into quarantine.
Im really worried that they've got that deadly frog disease and have infected my frogs.

Stupid me not quarantining first :[

I have put the new frogs in another tank with a filter and heater. It's not cycled but they're not moving anyway. They're still alive but floating on the top in the corners. I know this is not ideal but im sure they must be Ill.

Does this sound like chyrid fungus? They we're in the tank for about 7 hrs.
Looking closely at them their stomachs look a bit bloodshot. One had a red mark on her hand but I thought maybe a newt had nipped her.

I've done a partial water change on my tank. How.else can I try and protect my old frogs?

woke this morning and both frogs were dead. floating upright against plasyic plants. they hadn't moved position since last night.
when I poked them to check they were dead they both floated and landed upside down.

I'm confused about what happened to them because they were both on the bottom of a relatively shallow well planted tank in the aquatic shop.
they were the only frogs left in a tank crammed with newts.

what does it sound like they died of? and are my other frogs at risk?

I know they were in a uncycled tank lasf night which is very bad. but they did look almost dead at that point anyway.

Hard to say, Ammonia at 0ppm is good but you need to test Nitrite and Nitrates too. Nitrites are actually more toxic than Ammonia.

If they were kept with Newts than that could have caused a problem, many Newts are toxic, long exposure to their toxins certainly could cause damage and shorten their life spans significantly. (this is just a guess, however)

If your LFS is mixing amphibian species that is kind of a bad sign... a LFS here had a vivarium with fire bellied toads, bullfrog tadpoles, african dwarf frogs all in one tank.. thankfully they've moved these species to separate tanks recently.. (but they don't carry bullfrog tadpoles anymore which is kind of a bummer..).

I'm taking a sample of my water to the lfs today to try and get a refund. they offered replacements but I really don't want to buy anything else from them.
my frogs seem fine atm but I'm really worried its that chytrid fungus that shows no symptoms for weeks or months.
when I examined the dead frogs bodies they both had skin that looked bumpy and ready to shed. one had a patch of skin missing from its back.

they were only put in a couple of inches of water in the sealed plastic bag to be transported home though.
would that cause an issue? my others were in much deeper water when bagged for the trip home.
