    Advice on eye!

    I changed the substrate yesterday to sand to help keep my Cory’s safe and when I returned them back from the holding tank that had their tank water in it, one of my baby Cory’s eye looks really bad.

    Breeding Pygmy Corydoras

    Hello all! I've been keeping pygmy corydoras for a few years because they are my favorite fish. I'd really like to see them reproduce but they don't seem to be doing so on their own. So what I'll do here is go through some of the steps I've been taking to get them to spawn and hopefully one of...

    Done with neon tetras, can you recommend other tankmates?

    So, I've got a 29g tank, already running for 4 months. Couple of months ago I bought a dozen neon tetras and within 2 days 5 died. Columnaris, NTD, or too much stress, never found out for sure. Fast forward to yesterday. I've had a planted and cycled "quarantine" tank running for 3 weeks now...

    Thinking I Need to Rehome My Fish

    I absolutely hate to think this but I honestly don’t know what else to do anymore besides just start over. I’ve made a lot of mistakes and really think they’re suffering for it and at this point, I don’t know what to do anymore. My only main problem rn is that I just don’t know how to go about...

    Trying to Figure Out if This is Ich or Not?

    Okay, so I’ve had a small 5 gal with glofish for years, and I upgraded to a 15 not too long ago. Maybe a month ish? I let it sit with plants and filter for a while before acclimating the 4 glo tetras I had into it (plus some snails), and about a week ago I got another tetra and 5 cory cats. I...

    Is swim bladder medication safe for corys?

    Hi, One of my cory catfish has swim bladder disease, so I just went out and bought a medication However, it says that it can't be used for scaleless fish. I know corys have "plates" instead of scales, so would it still be safe to use? Thanks very much, any help would be appreciated

    Will my Corys be happy? HELP A NOOB

    I am new to the hobby and I was told my Corys will be happy as long as I get at least 4. I asked if they need to be the same species and I was told that they don’t, so I got two Julli and two Peppered Corys. BUT I have been reading that they will not technically school together. They seem to be...

    question about substrates

    Hi, everyone. can I take beach sand for example and just boil it to kill any microbes and bacteria in it or should I buy purpose-made sand substrates? I am in need of a sandy bottom in my big tank for barbs like corys.

I have 4 albino corys, 2 emerald. Is this a feasible combination or should I just skip out on the crayfish? I...
