Frequent fish deaths - advice needed!

[Naughts]

I'm assuming now would be a good time to add that salt as I think you suggested?

I’ve read that salt (or any fish medication) should not be used in tanks with frogs.

Yes, I agree... Salt will draw water off their bodies and can cause dehydration in addition of electrolyte imbalance and skin irritation.

Correct! Please don't add salt unless you can move your frog out! You'd need to keep them separate until the salt is completely diluted out of the tank.

Yeah I thought that was the case. I won't be adding salt for now anyway

The loach and molly should both reach about 4 inches long when mature and that along with the guppies and frog are probably all you want in the tank. You could probably squeeze in another frog if it's a small species. If you get rid of the molly you could add other stuff.

Post a picture of the loach and the algae. Most loaches don't eat algae.

Algae grows when there is an imbalance in the light, nutrients and plants.
Too much light or nutrients and the algae grows.
Not enough live plants to use the light and nutrients and algae grows.
Normally reducing the nutrients with big water changes and gravel cleaning, and reducing aquarium plant fertiliser (if you use any) can reduce the algae. Adding live plants will also reduce algae. But post a picture of the algae first so we know what we're dealing with.

If you were going to add salt you should have done it straight away. Right now it's unlikely to make any difference unless more fish are unwell.

The best thing to do if fish get sick or after a fish dies is
1) wipe the inside of the glass to remove the biofilm (slime).

2) do a huge (75%) water change and gravel clean the substrate to dilute any pathogens in the water.

3) clean the filter if it hasn't been done in the last 2 weeks.

Thanks for the info. I will leave them as they are for a month or so then get another frog I expect.

Luckily I've already done a big water change and gravel/filter clean after the last death. So I will be patient and see what happens over the next month.
I will post a picture of the loach later but was told it feeds on the algae. Perhaps it's not a loach, it might be my mistake. I cleaned most of the algae off during the water change etc so nothing to show at the moment. It wasn't an awful lot, but just noticed its increased a bit

Unfortunately it now appears that molly is about to die too. Been at the bottom of the tank yesterday evening and today. There's clearly an issue so I think I'm going to have to wait for them all to die and then start again

Picture and video of the sick fish.
Upload video to YouTube, then copy & paste the link here.
If you use a mobile phone to film the fish, hold the phone horizontally (landscape mode) so the footage fills the entire screen and doesn't have black bars on either end.

Was the molly eating well yesterday?
What does its poop look like?
Is it bloated up at all?
Is it breathing heavily/ rapidly?
