Hello,
I am back to my aquarium hobby as I love fishes and it relaxes me to just watch them swim.
I did a lot of reading on nitrogen cycle and fish care before adding fish to the tank but stuff happens and when there are live fishes actions needs to be taken very fast.
I got a 40 Gallon breeder and have below fishes:
8 Neon Tetras
2 White Mollys
2 Dwarf Gaurami
2 Cory Catfish
5 Zebra Danios
Recently added one male betta to see if they would be compatible. But ever since I got the betta he has been laying low.
intially I thought it will adjust slowly as he was all alone in that small cup.
On closely monitoring I found yellow patches on him so have isolated him and added mela mix.
today I observed my zebra danios are also having yellow patches(Image attached)
I had cycled the tanks more more than a month using fisheless cycling. Using Fritz liquids and confirmed water parameters using master kit. During water change after getting fish the cycle for reset causing an ammonia spike. Now I am able to see the nirites and nitrates which are on lower side. Will perform a water change but wanted to get some guidance which medication is recommended as I am worried all my fishes might be infected.
