so, this is my first time using fish lore. Idk if anyone will see this, but I need help with my new dwarf frogs. I'm a complete newbie so I've never had a real aquarium before, so far everything's somewhat okay with my water quality. I got my frogs about 3 days ago, I have a 10 gallon tank with 2 dwarf frogs (getting one more soon) Obviously before getting the frogs I did lots of research on starting my tank. I was having trouble with my water quality because no matter how many water changes I did with multiple kinds of water AND water conditioner/stress zyme added; the nitrites were still high. Like in the stress range, not dangerously high. I guess it's due to the water quality here in florida but I can't seem to get rid of it. The nitrite range was low enough for me to get the frogs(according to the store). They have been fine, very active and eating. Except for one of them. He seems very stressed out and keeps swimming up and down the corners of my tank, especially where the filter is. He dislikes the current but decides to go there anyway. He really seems bothered by soemthing, it could be the nitrite level. If it was though, I'm pretty sure my other one would be acting strange as well, but he's always calm and acts normal. The unhappy one is extra agitated today. and I haven't seen him eat since I got him. Any advice?? I also did another water test today and everything was fine except the nitrite still being slightly high as well as 0 nitrates. I do not have any fish, just the 2 frogs. The temperature is at a constant 76°. I have gravel substrate and only artificial plants.
