  1. Stocking advice for a 10gal?

    Freshwater and Tropical Fish
    Hiya! So I have a question that requires just a tiny bit of background. I have a 10 gallon tank that currently contains 4 sterbai corydoras. They're happy, healthy, and active at a temperature of 76-77 °F. The tank is planted, not super heavily but the hornwort and (what I believe is) purple...

  3. Persistent Fin Rot on Corydoras (1 year)

    Tropical Fish Diseases
    I bought an albino cory at a Petsmart about a year ago. He wasn't in the best condition, but I figured that once he went into a good tank, he would eventually heal up. Well, I've had this particular cory for about 1 year now, and he is not getting any better. His fins, especially his tail...
  4. Albino Cory Swimming at the Surface

    Catfish
    So after I did a water change, my albino cory was showing off some weird behavior today, which I've never seen in a cory before! Instead of hanging out on the sand with the other cories, he decided to stay at the surface of the water. I know they tag the surface to get air, sometimes even swim...

    Catfish
    I have 5 fish I bought as Corydoras Aeneus, 3 Albino Cories and 2 Green Cories (two separate fish stores). Can anyone with experience please confirm these are indeed Corydoras Aeneus. The pictures are not perfect quality, but should be sufficient: Thank you!
  6. Stocking a 20g with Tetras, Corydoras, and what else?

    Beginner Freshwater Aquarium
    I'm setting up a new 20g tank and when it finishes cycling, I'm adding in my existing 5 neon tetras and 5 corydoras. I also have some plants in the tank (not sure of their names). Is there any other species I can add to the tank? On AqAdvisor it says the tank's stocking level would be 53%...
  7. Treating Fin Rot with Melafix & High Nitrates

    Tropical Fish Diseases
    One of my corydoras has fin rot on its tail and is acting lethargic. All levels are normal except for nitrates which are high (~50ppm)... I immediately did a 50% water change and am going out to buy some Melafix. Now I've read that daily water changes are important to bring the nitrate...
  8. Corydoras Or Loaches?

    Catfish
    So, i want to get some sort of fish that is a bottom dweller for my 29 gallon. the question is, should i get cories or zebra/kuhli loaches? I really like both, but would the loaches hurt my 2 african dwarf frogs? Any feedback is welcome, thanks!:-D
  9. New Planted Tank - fishes?

    Freshwater and Tropical Fish
    Hi guys, I'm setting up a new tank and had a few questions. I've never had a tank with very many (if any) live plants as I've always had more aggressive fish who like to rip them out and eat/destroy them. This week I'm setting up a new tank, it's 40-55g (I'll post exact size later when I get a...

    Hello, I bought a new albino cory cat a few days ago, and lately he has been very lethargic. not sure what is wrong so I decided to see what you guys think. However just as I started typing this, he began to roll around on the sand floor and have a LOT of difficulty swimming - he is definitely...
  11. aquarium salt and corys

    Catfish
    My corys have got red base on the fins at the moment which has come from my tetras which i can't get rid of. My cory got a cut the other week and now has caught it from the water. It seems to have spread to my other large corys. I have never used aquarium salt but just ordered some to hopefully...
  12. Preparing for Corys, have some questions

    Catfish
    A fish store near me has recently started carrying what they call Julii corys. I've completely fallen in love with them and want to add them to my tank! However, based on what I remember about the fish at the store, I think the so-called "juliis" actually looked like C. trilineatus (now that I'm...

  14. i fail at keeping corys...

    Catfish
    When I first started keeping fish, corys were my first fish. I had bronze corys first, then, later, peppered corys. Since I didn't really know what I was doing back then, the bronzies weren't a huge success, although it's amazing they lived as long as they did considering how I treated them. The...

  18. myxazin safe for corys?

    Freshwater and Tropical Fish
    A couple of my corys have a little bit of fin rot and I want to stop it from getting worse as soon ASAP. I've used Myxazin before to treat fin rot, but I've always used a half dose because the first time I tried the full dose my tetras seemed to get really stressed out, and I've never used it...
