What I would do as you have large leaves is cut one leaf in half add half to each side to each side of the tank

to get a beneficial effect I would add one leaf per gallon

The tannins are very beneficial most Betta breeder's use Indian almond leaves

What I would do is add some Indian almond leaves as they have antibacterial and antifungal properties and I would treat with aquarium salt 1 table spoon for 2 gallons for just remember to only put back in what you take out so if you do a two gallon water change put 1 table spoon of salt back in the salt will help with the fin rot and treat any possible ich am not convinced your fish has ich give an update after a week if your seeing no improvement @KerrieBetta2

Am struggling to see ich on your fish that would look like sprinkling of small flat white spots on the fins and body rarely on the eyes a litter more information would be helpful what are your water parameters ammonia nitrite nitrate pH temperature is he eating ok any rapid breathing @KerrieBetta2

love natural colouration over captive bred Colour morph lot more subtle but stunning

Catnip will do wonders

Definitely need treating I would throw everything at them except the kitchen sink

What I would do is get a cheap sponge filter move him to the 10 gallon tank and keep close eye on your water parameters and water change as needed then redose the salt and ick x

Could be saprolegniasis it's a water mould what I would do is quarantine and treat with a combination of ick X and aquarium salt 1 table spoon for 1 gallon active ingredient in ick X malachite green and aquarium salt are an effective treatment for saprolegniasis @FishMama814

It could be a number of things a cyst or an encapsulated nematode worm it could have a bacterial component what I would do is quarantine and treat with aquarium salt 1 table spoon for 2 gallons just remember to only put back in what you take out so that if you do a 2 gallon water change put 1 table spoon of salt back in I would do that for 1 week you could also add some Indian almond leaves as they have antibacterial and antifungal properties add an extra air stone during treatment give an update after a week if your seeing no improvement@flyingcow

What I would do is treat with aquarium salt 1 table spoon for 2 gallons and do a course of kanaplex just remember to only add back in the amount of salt you take out so if you do a two gallon water change put 1 table spoon of salt back in and add an extra air stone during treatment give an update after the course of kanaplex

Could be over production of the slime coat that can be caused by a number of things a parasitic infections poor water quality it might just be my eyes does it have tiny white spots near the eyes did you quarantine the new fish before adding it to the main tank any rapid breathing hanging out near the surface lethargy flashing erratic swimming @Pumpkinstine

What are your water parameters ammonia nitrite nitrate pH KH GH temperature have you got a picture from a different angle it's difficult to tell what's going on @Pumpkinstine

Just bad luck you've had your fair share and it should be plain sailing from now on I have had heaters fail no leaks fingers crossed

If the vents swollen and red that could be caused by a parasitic infections possible camallanus worms what I would do is treat once a week for three weeks with expel p just remember to blackout the tank during treatment as the active ingredient levamisole is light sensitive @JakesAquariums

He's a recipe for maracyn2 in food

@AndyR

I use one on my 50 gallon it heavily stock has about a 150 bristlenose plecos of various sizes so I clean the prefilter once a week it only takes a couple of minutes to clean if my tank was lightly stock you could probably only have to clean the prefilter once a month

Oase biomaster Thermo are good quality canister filters easy to clean prefilter so don't have to clean the canister filter as often with a built in heater so you don't have a heater in the tank

Levamisole can be harmful to invertebrates praziquantel at the recommended dose shouldn't harm your snails or shrimp I would always air on the side of caution and remove your snails and shrimp during treatment

Small active fish need feeding more frequently I would feed a minimum of once a day I feed my tetras twice a day what I would do is get holed of Esha gdex active ingredient is praziquantel and follow this treatment protocol for parasitic infections treating with praziquantel and levamisole will treat a wide range parasites give a more broad spectrum treatment

Any white stingy poop what are you feeding and how often

Esha ndx has the same active ingredient as expel p levamisole have you notice any rapid breathing hanging near the surface lethargy flashing spitting food out loss of appetite sunken belly

What are your water parameters ammonia nitrite nitrate pH KH just case something off looking at the picture I would quarantine and treat with kanaplex and aquarium salt 1 table spoon for 2 gallons the salt will help reduce fluid buildup in the eye could a fin rot or an injury to the tail it could be bacterial that's why I recommended kanaplex it's a broad spectrum antibiotic treatment @anitstuk
