The reddening can be a sign of an infection setting in that why I would do a course of maracyn2 in food

I wouldn't recommend mixing that many medication what I would do is water changes and add active carbon for 24hr to remover the other medications before treating for anchor worms

It's more than likely damage due to nitirte spike what I would do is a course of maracyn2 active is minocycline in food I use a quarter of a packet of maracyn2 1 table spoon of pellets one scoop of seachems focus 1 cap of garlic guard a few drops of water mix well feed a small amount twice daily for 7 days store any leftover medicated food in the fridge

It's difficult to tell off that picture if it's anchor worms he some information increase you need to treat

Good to hear he's recovering

You could put a in their sponge filter or just use an air stone if you have some seeded filter media that would help

With most tetras it depends on lighting and good quality food will improve they colour lemon tetras can look washed out under bright lights

I would just treat with ick x for fungal infections it always best to Qarantine when it's only one sick as exposing healthy fish to unnecessary treatment is good in the long run

High levels of nitrates can effect fish immune system coupled with the ammonia are probably the cause daily water changes and add a double dose of prime to detoxify any ammonia or nitrites till it gets to zero if you can get a 5 gallon tank or you can use a plastic tote to Qarantine him the most effective treatment I have found for Dropsy is kanaplex dose the tank to treat any possible bacterial infections metroplex in food feeding a small amount twice a day for 3 weeks treats aeromonas bacteria a common cause of Dropsy and aquarium salt 1 table spoon for 2 gallons to help reduce the fluid buildup or you can do Epsom salt baths 1 table spoon for 2 gallons for no more than 15 minutes @ChanMan

It's possible he has internal crush injurys I would Qarantine and add a small amount of aquarium salt 1 table spoon for 3 gallons the the will aid Gill function and add essential electrolytes to help him recover and monitor

What are your water parameters and can you take a picture of the sick fish and how long has he had symptoms such as pineconing

I would raise the temperature to 80F I wouldn't treat with melafix or primafix they are oil base herbal treatments and not good for fish with labyrinth organs such as Bettas gourami's aren't very effective treatment they are like a mild antiseptic treatment at best I would start feeding him again a small amount of frozen daphnia or brine shrimp and add a small amount of aquarium salt to his 1 table spoon for 3 gallons they Will aid in Gill function and add essential electrolytes is he having any trouble swimming such as swimming to the top of the tank and just floating back down

What are your water parameters ammonia nitirte etc and have you noticed him pass anything resently and what temperature do you keep his tank at

Any rapid breathing white stringy poop

It either bacterial or viral what I would do is aid an extra air stone and treat with kanaplex in food and aquarium salt 1 table spoon for 3 the salt will aid Gill function and add essential electrolytes

I agree doesn't look like ammonia it could be hemorrhagic septicemia or a bacterial infection I would treat with kanaplex in food

It's possible pH fluctuations are affecting them as guppies like a pH of 7.5 the daily fluctuations could be stressing them out affecting their immune system also bent spine's can be caused by to low a kH what I would do is add an extra air stone stone add some crushed coral to increase your kH

It could be swim bladder most common causes are over eating and the stomach putting pressure on the swim bladder or constipation or bacterial infection or an injury what I would do Epsom salt baths 1 table spoon for 2 gallons for no more than 15 minutes for a couple of days as Epsom salt acts as a muscle relaxants to relieve pressure on the swim bladder if you notice no improvement after after 5 days or he gets worse than I would do a course of kanaplex in food I missed the nitrates if it's 70 that would affect the fish immune system and effective the swim bladder I would do daily water changes and add prime to detoxify any nitrites

Good to hear he's recoved and has a nice new home

It's possible the dominant male is bullying the smaller male causing injurys to the scales

Looks like an injury I would do a course of maracyn and monitor if it starts to get worse or a fuzzy appearance then I would treat maracyn and ick x together

What I would do is small daily water changes to dilute the ammonia and nitirte and keep adding safe to detoxify any ammonia or nitrites they probably came in in a weaken state as the ammonia and nitirte have spiked that could be pushing the remaining cardinals over the edge I would also add some Aquarium salt 1 table spoon for 5 gallons that will aid Gill function and add essential electrolytes at this point getting ammonia and nitirte to zero will give your fish best chance at a recovery

Could be a tumor or a benign growth primafix is a herbal treatment only effective as a mild antiseptic treatment at best what I would do is treat with maracyn2 active ingredient is minocycline that has proven effective at sinking some types of lumps in food use 1 quarter of a packet of maracyn2 1 table spoon of pellets one scoop of seachems focus 1 cap of garlic guard a few drops of water mix well feed a small amount twice store any leftover medicated food in the fridge and aquarium salt 1 table spoon for 2 gallons

Love the terrestrial growth stunning tank
