  1. Help with sick fish

    Tropical Fish Diseases
    We had a 55 gal tank with 2 comets and 1 tetra. Yesterday we were out cruising around and decided to stop by our local pet store to look around. We ended up buying 1 lion head and 1 fancy goldfish. (We asked if they could be put in the tank with the other fish and they said yes) We introduced...
  2. Red Tail Shark Discoloring. Should I do frequent water change on my newly setup tank?

    Beginner Freshwater Aquarium
    Hello guys. I just set up my tank about 10 days ago. I have a pair or dwarf gouramis and a red tail shark there. But the red tail shark is discoloring. It's not as dark black and its tail is also getting transparent :-( I cant get a water test kit where I am. So should I do frequent water...

    Beginner Freshwater Aquarium
    Hi, I am fairly new to the amazing hobby of fish keeping. It has been a month and it is time for a water change, and filter clean up. Now I was wondering what to do with the black bio sponge (where the beneficial bacteria are). Do I dispose of it or do I keep it there forever? Thanks Guys...

  6. Temperature Shock?

    Beginner Freshwater Aquarium
    I lost a 6 month old Zebra Danio today following a routine 25% weekly water change. He shared a 20-gal tank with two other Danios and six tetras (Rosie and Red Phantom). The whole gang seemed fine before the water change, but all were acting panicked right after. My first thought was to look...

  9. Double Water Change... Safe?

    Beginner Freshwater Aquarium
    I'm doing daily water changes in an attempt to reduce NitrIte in my new 20-gal freshwater tank. The tank has been running for a total of fourteen days, and fish have been in it for ten. Ammonia is under 0.25ppm, but NitrIte has been 5ppm or higher for a week. Today, I did a 40% water change...

    Tropical Fish Diseases
    Hi - I did a large water change today (accidentally). I was going to do a 30% water change, as I do weekly, but I took my eye off the siphon and the bucket overflowed, and I ended up doing a 75% water change. The tank is a 20 gallon high, with Ammonia 0, Nitrite 0 and Nitrates 15. Ph is 7.6...
  11. Water Change Question

    Beginner Freshwater Aquarium
    I was in the middle of doing a 50% water change when I noticed a complicaton. I unplug my filter during the water change and I noticed that the water level was so low that there was very little water in the filter, and I realized that beneficial bacteria needed to be wet to survive. Not wanting...

  13. disease contagiousness

    Tropical Fish Diseases
    Hi! I'm wondering if anyone out there has any information on fish diseases and their contagiousness. If you have a tank with a sick fish, in my case, a fungal infection, does that mean that all of the other fish will potentially get it? After quarantining a sick fish, what can you do to ensure...
  14. Algae bloom hours after water change

    Beginner Freshwater Aquarium
    Hey guys I've been having problems with algae in my 80 gallon tank for about a month now. I got plants, reduced light, eased up on feeding and it's helped, but the water still gets a little greenish. The really frustrating thing is that i've been doing a 50% water change every week to clear it...
  15. Is water changing as easy as it seems?

    Beginner Freshwater Aquarium
    Hi everyone! So, I know this is a silly question (I warned y'all!) but whenever I take the hood off of my fish tank to change the water, all my black skirt tetras turn gray (that's what they do when they're stressed) and school. It would be cute, if I didn't know that it's possible to kill a...

  17. water changes in planted tank

    Beginner Freshwater Aquarium
    Hey all, First, when doing a water change I usually notice what I think some people call a "bacteria bloom". The water gets super cloudy and usually stays cloudy for a few days. My tap has tested for slight amounts of ammonia so I got Seachem's Prime (this is the first time I've used it--just...
  18. "spit back" with Fluval 305 canister water change

    Beginner Freshwater Aquarium
    Hey all, so I just did a water change and cleaned the canister too. The unique part of the fluval is there's a stop valve that allows you to keep water in the connected hoses for an easier transition (my explanation may be off). Problem is, when I cleaned the canister I drained the water...

    Cichlids
