    White marks

    I think my Cory has an infection or something. It appears to have white raised marks on its side. Any idea what I could do to treat? Should I separate it from the rest of the tank? All parameters are in range tank has been set up for over a year, these Cordy have been in for 6 months to a year...

    Cory Floating upside down

    Hi, my Venezuelan Cory has been acting strange since yesterday, when I found it floating at the top of the tank getting pushed around slowly by the flow. I thought that it was dead so I went to pick it up with the net and it zoomed away. It did the same thing today and was swimming upside down...

    Frozen brine shrimp vs bloodworms

    I have ember tetras, cory's and a betta in my 105l tank. I was thinking about adding some frozen food to their diets. Is there any nutritional differences between the frozen bloodworms and brine shrimp? I'm mostly thinking about the frozen food for the betta to be honest, I was thinking...

    I Need Some Quick Reasurance!

    Hello everyone! I'm not particularly stressed, but I'm just curious and slightly worried about one of my albino female corydoras. She had a red spot that faded to black on her egg area around a week ago, but it's completely gone now and she was lethargic for one day but instantly improved (it...

    Should I replace my lost corycat?

    I lost one of my three peppered corycats today. Since my once tiny school is now a pair, should I replace the lost cory? If so, will a new peppered cory school well with the other two (who I’ve had for about a year)? I also have 3 oto cats, 5 harlequin rasboras, and a honey Gourami in the tank...

    L181 pleco and Corydoras Venezuela Black

    I have bought 5 L181 pleco - naturally they are quarantined in a separate tank, but when they are ready to be moved out of quarantine I want to place them together with my Corydoras Venezuela Black. Is this a good combo? I don’t want to risk my corys lives or their fins being bitten of

    Stocking a 450L

    Evening everyone, My 450L (approx 119 US gallon) recently finished cycling. 150 x 50 x 60cm. I'm in the process of slowly stocking it over the next few months. I've not run a tank of this size before so I'm feeling my way in with the stocking levels. At the moment, it has two Siamese Algae...

    55 gallon stocking ideas with Black Skirt Tetras

    Hi all, I've gone back and forth with my stocking ideas and people on the forums have been super helpful so far but I find myself lost again. I currently have a 55 gallon that is lightly planted (hoping to continually add plants over time) with some driftwood as well. Currently there are 7...

    Brand new cory catfish with possible swim bladder. Help!

    I just got 2 new luxozonas cory cats. One of them is doing great and the other was rough from the start. He swam through some bubbles and looked a little wobbly. Then he was just laying on the bottom. After a while I noticed him having a hard time keeping himself straight. Eventually he was...

    Is this white spot? (Ich)

    Hi guys, so I put a new Cory into my tank yesterday and noticed a white spot just below the fin. Is this ich or something else? I cannot tell but should I be worried? Thank you, Brandon.

    Sick Cory

    One of my Cory's is suddenly unable to swim correctly and is sat at the bottom of the tank all day. If it does try and swim it sort of bounces about at the bottom of the tank and takes a while to right itself if it falls on its side or upside down. Iv checked water parameters and all are spot on...

    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.

    Dwarf Mexican Crayfish and Corys?

    I’m thinking about adding a Dwarf Mexican Crayfish to my established 20 tall killifish and Cory tank. I’ve seen conflicting opinions on whether the crayfish will harass/eat the corys. I have 4 albino corys, 2 emerald. Is this a feasible combination or should I just skip out on the crayfish? I...

    BN Peco behaviour

    Hey all its been a while since I've posted because my 34 gallon is finally stocked and all was well. However, my juvenile bushynose pleco (I got when he was just weeks old.) is about 4 months now, and is the tank bully. Still not sure of the sex because it's still young. When he eats, he hogs...

This was a couple of years ago and 2 have died I want to get him a group but have not seen any like him...

    Sick Bronze Corydora

    I've already lost one Cory to this and I don't want to lose another, hoping someone can help. I got these 2 at the same time a while ago and got an extra 4 more recently. Basically, both of the older corys had what I assumed to be swim bladder issues since they were using leaves to avoid...

    Upgrading to a 20 gallon!

    I'm very excited as I am upgrading my 10 gallon to a 20 gallon. I currently have three adult (two female, one male) gardneri killifish and 6 corys (4 albino, 2 emerald), and two nerite snails.

    Hi I am new to the forum, I have a 29g tank that has been fully cycled for about 4 months. I have sand but no live plants. I have 5 guppys and 5 bronze corys. About a week and a half ago I noticed one of my corys looked like it had the early signs of fin rot. I checked the nitrates with the...
