Yesturday I brought 3 Zebra dineos to cycle my 10 gallon tank I filled it up with water, and water conditioner. I have lots of fake plants and rocks for them to hide in. I have a betta fish as-well, and he was in a 1.5 gallon tank. I noticed that h looked very stressed and started to stay on the bottom of the tank, I even noticed what I think s fin rot. I decided to put him inside the 10 gallon tank with the 3 zebra dianos. Will this be ok for all four those fish to cycle the tan or should I put the betta back in his small tank?
If he has fin rot, get him out of the tank and back into the 1.5. Start treating him with salt baths to start. Use a little salt in the 1.5 gallon too. Keep him warm, around a STEADY 78-80 degrees F. This should help, once he is mostly healed and showing signs of regrowth, then he can go back into the 10 gallon.
