vimandvigrrrpet 35 Posted August 20, 2017 I got two new large oranda's about 2 months ago. They have been very vigorous...seem happy. But about 4 days ago I saw some black spots on one of them. The tank is 30 gallons. I have a tiny oranda and a tiny pearlacale in the same tank while I find another 30 gallon at a decent price. There are no love plants. I use the API master test kit. Ph: 6.8 ammonia: 25ppm, nitrite: zero, nitrate: zero. Sent from my LG-H812 using Tapatalk 0 Quote Share this post Link to post Share on other sites
