sounds like new environment zoomies nothing I would worry about

Corydoras will help keep your substrate clean, Julii corydoras will probably fit your theme more, Otos will clean your plants of algae. Apistogrammas or gouramis could be a cool centerpiece fish. Schooling fish could include cardinal or neon or rummy nose tetras.

Breeding Panda Corydoras Breeding panda corydoras is achievable in a home aquarium (https://www.youtube.com/watch?v=uEn202Y2FfE) Here's a general guide: Setting up the breeding tank: Size: A small tank (10-15 gallons) is suitable for breeding purposes. Water: Mimic their natural habitat with slightly acidic soft water (pH 6.0-7.0) and a cooler temperature (72-75°F) than the main tank. Substrate: Use smooth sand or fine gravel to avoid injuring their barbels. Hiding spots: Provide caves or driftwood for the fish to feel secure. Spawning medium (optional): Add spawning mops or plants with fine leaves where they can lay eggs. Sexing Panda Corydoras: Body shape: Females tend to be wider and rounder, especially when full of eggs. Males are slimmer with a more pointed dorsal fin. Fins: Males have a more pronounced pointed anal fin than females. Breeding process: Conditioning: Separate a healthy group (6-8) with a mix of males and females. Feed them high-quality live or frozen foods like brine shrimp or bloodworms to encourage breeding. (https://www.thesprucepets.com/panda-cory-1380838) Trigger spawning: Simulate rainy season conditions with a large water change (50%) using cooler water. Spawning: The males will chase the females, and if successful, fertilization will occur externally. The female will scatter the eggs about the tank. Raising fry: Separate parents: After spawning, remove the adults to prevent them from eating the eggs. Egg care: The eggs hatch in 3-5 days. Fungus can be a problem, so methylene blue (aquarium-safe dose) can be used as a preventative measure. However, follow dosage instructions carefully. Feeding fry: Infusoria are ideal for the first few days. Microworms or baby brine shrimp can be offered as they grow. Water quality: Maintain pristine water conditions with frequent small water changes. Important notes: Breeding fish can be time-consuming and require adjustments to your existing setup. Ensure you have a plan for the fry before breeding, as they can be difficult to raise and unwanted fry can be challenging to rehome.

Please consult this Blog as it relates to your problem: https://www.aquariumcoop.com/blogs/aquarium/fish-fungus As I said b4 I am not entirely qualified to be giving you medication recommendations but I do hope this article helps and our disease experts will hopefully respond soon 🤞

@Colu Is the disease expert I believe. To me this looks like a fungal infection. The 80 degree water could speed up the infection so until someone more qualified can give you better advice I would say turn that down to 76-77 degrees. Welcome to the Forum btw

Keep us updated if it gets worse or better.

@BIRD0887 -Mystery snails are omnivores, so they get nutrients from both plants and animals. They'll happily munch on algae in your tank, but you can also supplement their diet with a variety of vegetables. Here are some safe options for your mystery snail: Blanched leafy greens: Romaine lettuce, spinach, kale Sliced vegetables: Cucumber, zucchini, squash, green beans Carrot slices (blanched or microwaved for softening) -Here are some tips for feeding your mystery snail vegetables: Wash them thoroughly before placing them in the tank. Blanch them briefly in boiling water to soften them up. This makes them easier for the snail to eat and helps them sink to the bottom of the tank. Cut them into small pieces that are easy for your snail to manage. Only put in a small amount at a time and remove any uneaten food after a day or two to avoid fouling the water. Also congrats on hatching your snails! Ask your local pet store if they would take them, sometimes they will even give you store credit for them! (Sorry for the lack of responses)

Black gravel will really bring out the color in any of your fish, especially if you get a betta fish (which I would 100% recommend btw) if you aren't getting a betta I would go with regular gravel or sand. Ive never done backgrounds b4 so I can't give you any suggestions on that. Send pictures when you can!

I don't wanna sound dumb bcs you might already know this, Dont just plop some tap water into your tank, it must be treated for chlorine first. Just an FYI if you didn't know

Java Ferns, they just make babies by themselves under their leaves. I have 1 Java fern and I can see at least 5 new plantlets (idk what imma do with them 😅)

Mystery snails enjoy eating leftover bits of fish food, biofilm and Diatoms aka Brown Algae. If you have an established tank you should have plenty of those, Corydoras like scavenging through your substrate and Plecos enjoy sucking of driftwood for Cellulose (helps em' digest stuff) and sucking on the glass for algae. I live in FL so I understand the Liquid rock water but that shouldn't affect the snails. If you could tell me the age of the snails that pass that would be appreciated. Some reasons why your snail passed away could be: -Lack of Calcium: They need Calcium help maintain their shell hardness -Poor water quality: Mystery snails are sensitive to water conditions. Build-up of ammonia, nitrites, or nitrates can be harmful. Regular water changes are important for keeping them healthy. -Inproper Diet: Mystery snails are scavengers but need a balanced diet. Offer them a variety of foods like algae wafers, blanched vegetables, and sinking fish food. -Temperature Variation: Mystery snails prefer cooler water temperatures, ideally between 68-78 degrees Fahrenheit (20-26 degrees Celsius).Sudden increases in water temperature can stress or shock them. They are cold-blooded but too warm of water could be harmful. -Old Age: Mystery snails will usually live for about 1-2 years. Hope this helps!

Just a thought... Maybe you could add a betta, many betta varieties are eye catching and with all that room, she (I think female bettas would do better than males as it is a community tank ) would really thrive. If you do decide on a betta fish may I suggest a Koi Betta, the reds and whites and teals really are exquisite imo. (picture for reference)

Wow, a month...I guess this guy isn't a sleepy boi. I def agree with GuppySnail something is inhibiting his ability to get some 02. The picture with his trapdoor open wide looks like a big improvement! Just make sure to keep that dish clean.

its poop lol

So I have a 20 gallon tank. It already has 1 green Cory in it. ive had him for 1-2 years and he is big, all the other green Cories at the store are tiny. Would it be ok to add the small Cories into the 20 gallon with the size difference? would they shoal together? he has been alone all this time and I dont want the shock of new friends scare him away from them.
