- - nitrite spike? (http://www.tropicalfishkeeping.com/beginner-freshwater-aquarium/nitrite-spike-69390/)
Hey guys, my tank finished cycling a little bit ago, like, 4 days ago. The past 3 days it had a 0 reading for ammonia and nitrite, but this morning I measured it and I had 0 ammonia, 5-10 nitrates, but 1-2 ppm reading of nitrite! I quickly did a pwc of 20%, but now the nitrites are reading at 0 ppm. I am currently treating that tank with primafix and melafix, as a few of my corys have torn fins, and 1 potentially has a fungus growth. I also did treat that tank with sea chem flourish yesterday for my plants. Its a 5 gallon with 5 corys in it *they're in quarantine, I don't plan on keeping them in there* with 3 bunches of anacharis plants. I also did a gravel vac today. I have been feeding them 2 times a day, with 3-5 sinking hikari discs each time as they pretty much devour all disks within 10 minutes. I did remove 1 bunch of anacharis however, as it seemed as if it was slowly dieing. Anyone might know why my nitrites jumped up so high with 0 ammonia reading and 0 nitrite reading just yesterday, and after just a 20% water change the nitrite reading is back down to 0? Could it have been a false reading? Thanks!
that sounds like a ton of food...
It is, but they eat it all within 5-10 minutes. If I feed them 4-5 wafers the first time, I only feed them 2-3 the second time in the day

Has this happened to anyone? Just wondering so I can adjust accordingly, or if its just a random happen-stance.
Nitrite spikes are nearly always preceded by ammonia spike which could be a result of WAY too much food or by disturbing the gravel to a degree that rotting food or plant matter which was in the gravel or sand was suddenly freed into the water column.
Cutting down on food by half will keep from poisoning the fish and gravel stay's cleaner.
A dozen cory's would not need half of what you are offering to just five in the way of food.
clean water and lot's of it is best medicine for fin rot and fungus both of which are related to poor water conditions.
Hmm. I'll cut back on the feeding, but what surprised me the most is the huge jump from 0 ppm to 1-2 ppm, and then after a 15-20% water change its back to 0 ppm. Struck me as kind of odd. Right now nitrites are at 0 ppm, so I think everything is fine. Just found it odd for such huge changes.
It may have been a false nitrite reading. If it was really at 2, your corys would have had difficulty respirating. Much more frequent trips to the surface for air, red gills, and general faster respiration and probably lethargy. If none of these symptoms occurred, I would suspect a false reading.
I agree with others, you are feeding way too much. A hungry fish is a healthy fish. Are those the smallish Hikari disks, about 1/4 inch across? I would only put in 3 of those each day, no more for 5 corys. Also, consider some other foods, variety is best for nutrition, alternating day to day. Two other types of sinking foods would work, and make sure one is plant-based (veggie) as this helps the intestinal tract. Frozen bloodworms would be a nice treat once or twice weekly in place of the prepared foods.
Thanks Byron. I'm going to pick up some omega onepelletz and hikari algae wafers. I used aqueon shrimp pellets as well. But they're always searching for food, and last night they were swimming around or eAting the anachAris plants I have in there. Is thAt normal?

They don't eat plants, they may injest plant bits and spit them out or pass them through the gills. But they do not digest plants, as far as I know, or at any rate not as a regular part of their diet.
Omega One are reputable foods. And Hikari. And all my substrate feeders (many cory species and loaches) go wild over Nutrafin sinking pellets.
Ok, just got some omega one shrimp pellets, and hikari algae wafers. I found it humorous that omega one "veggie" wafers would contain salmon, halibut, and other fish as part of the mix. So much for being a pure veggie wafer! Haha. But where can you get nutrafin sinking pellets? I can't find them anywhere. Only nutrafin flake style food.
