    Hi all, Thanks so much for all your advice on this forum! I'm new to keeping fish and have a 5.5 gallon tank with a 1 pepper cory, 1 green cory and 1 albino cory. The pet store said that they wouldn't know the difference between species and would school - now I'm not so sure. I would love your...

    Hi All, I'm a new fish owner and new to the forum. Great to meet you! So I got a 5.5 galloon starter kit at PetSmart and three cories. I now realize after being on the forum for a couple of days that this is likely too small a tank for 3 fish? Though they said at PetSmart that was fine and I...

    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...

    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...

    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...

  7. Cichlids
    I have a 125 gallon tank stocked with assorted African cichlids. They average about 2-3 inches in length right now and there are currently 12 in there. Every week I change out roughly 20-25 gallons. Is this sufficient? Also, I have been feeding them once a day but notice that they always...

    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...

    I have 1 siamese and 1 molly in 20 litre tank. I had already cycled my tank before adding them. Since I had added them into tank all the water level had spike again I have done water change but still I have no luck I also have added ammonia lock which has lowered the ph level but has...

    I tested my water today and it was Ph: 6.0 Ammonia 8ppm Nitrite 0ppm Nitrate 0ppm I noticed my ammonia hasn't drop down yet, I have done 5 water changes and had added API ammonia lock. What should I do? . What if I get snail would that help lower levels or is it too high for the snail? I have...

    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...

    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...

    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...

    So here's a little history. I bought the Danio's as cycling fish, yes i know i shouldn't have but i was a complete noob at that time. that was back in January. They all survived the cycling process. and a few months after it was fully cycled They've been slowly dying off one by one. It's...

    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...

    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...

    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...

    its been a while since i have cycled a tank and i'm not sure how often to do a water change. my new 26 gallon has been running a week now and i know it is cycling because i have had nitrite readings of 0.5 that have come and gone. I have 6 fish in it right now and nothing has died or looked...

    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...

    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...
