No, it’s not coloring. They are like divots.
Thanks. What you said is exactly my plan. The guppies aren’t looking good at all this morning (get got rocks from the sick tank), so I think they’re goners, too. So I’ll clean both the tanks and cycle them properly.
Thank you!!!!! Giddy-up…….…
(after cycling). LOL!!
Yes, absolutely. You understand me perfectly. Healthy fish carry harmless amounts of a variety of different bacteria and other microlife, and still others come in with plants or even just drift in in the air.Fae
Thank you! So please let me see if I’m hearing this correctly….. even if I bleach the tank and all it’s contents, columnaris bacteria will still eventually make it’s way back into the tank. The differentiating factor in new fish contracting the infection or not is their immunity and stress level?
