You can add Aquarium salt with the medicate food I would just add 1 table spoon for 3 gallons

What are your water parameters as fin rot is commonly caused by poor water quality it looks like mild fin rot I would increase water changes and add some Indian almond leaves as they have antibacterial and antifungal properties you will need to add 1 leaf per gallon to get a beneficial effect if you notice his fins getting worse after a week then I would do a course of kanaplex in food if you add it to food you won't need to remove your active carbon from your filter and it's more effective treatment

What's your kH because what your describing could lack of minerals such as calcium in your water

Most cases of hole the head are bought on by a combination of poor diet poor water quality and Hexamita parasites the best treatment metronidazole that the active ingredient in seachems metroplex in food or you can treat with general cure or paracleanse

If you can Qarantine then you can add a high level of Aquarium salt 1 table spoon for 1 gallon to his tank and would still do the once a day as your in Canada and your treatment options are limited that the most effective treatment you can do thing's like melafix and primafix won't do much they are more like a mild antiseptic treatment

When adding antibiotic treatment to repashy they are not very heat resistant so mix the repashy till it starts to thicken then quickly mix in the antibiotic before adding to a mold

It's difficult to tell off your pictures if it's eye swollen if It is then i would do Epsom salt baths 1 table spoon for 1 gallon for no more than 15 minutes twice a day for a couple of days it will help to reduce the swelling

That usually caused by condensation on the leaves and high humidity above the water line causing them to rot I don't think that has anything to do with your Betta's eye issue I would just remove any leaves that develope fungus

Frist I would get a kH test aquarium co-op 6 in1 test strips test pH kH GH nitrates and nitrites and chorine API kH test kits what I use without noing your kH it difficult to no if it's water related or not if you have a pH below 7 you more than likely have low kH I would add some crushed coral in a media bag to your filter to raise your kH

What your kH at as low levels of minerals in your water can cause bent spine's livebearers

A little information would be helpful what are your water parameters and is he eating ok

I wouldn't use kanaplex and erythromycin together you can add kanaplex to his food for a more effective treatment I would use repashy instead of pellets to make the medicated food

What your ammonia reading at possible ammonia or bacterial infections I would definitely do a course of kanaplex as it a more broad spectrum antibiotic that adsorbed thought the skin and gills wear as erythromycin only treats external bacterial infections unless added to food

A low dose of Aquarium salt 1 table spoon for 10 gallons should help reduce any possible fluid buildup and won't harm your plants and I would do a course of kanaplex in food feed twice a day for 7 days

You could try frozen blood worms or daphnia earthworms crickets offer a variety of food eventually you will find something he likes

What I would do is start treating with kanaplex in food that shouldn't effect your shrimp also sera baktopur direct tables active ingredient is nifurpirinol broad spectrum antibiotic is shrimp Safe if you can't Qarantine I wouldn't use nitrofurazone based medication as that can harm your shrimp just kanaplex in food if it is Columnaris the level of salt you would need to use would kill your plants

Possible Columnaris the most effective treatment is a combination of kanaplex and jungal fungas clear fizz tabs containing nitrofurazone together following this treatment schedule using jungal fungas clear that of furan2 as it has been discontinued I would Qarantine your fish and treat as nitrofurazone isn't shrimp Safe

It can take a couple of days before you start to see any improvement

Welcome to the forum nice scapes

Welcome to the forum

Sorry to hear that they didn't make at least you did the best you could for them sometimes thing are just out of are control and no Matter what you do theirs not a good out come

If levamisole doesn't work you can treat with fenbendazole in food he's a couple of medication containing fenbendazole you can also use panacur c as it contains fenbendazole

It could be an injury or bacterial infection what I would do is add a small amount of aquarium salt 1 table spoon for 10 gallons that won't harm your plants at that level and treat with kanaplex in food that should cover all bases

You could use kanaplex in food and high level of Aquarium salt 1 table spoon for 1 gallon for 1 week if you can't get nitrofurazone based medication

I personally wouldn't add more fish your Bala sharks will get 12-14in and your other fish have some growing to do I would wait till they bigger then make a decision about reducing or increasing stocking
