I have a 200L aquarium filtered by an Ehiem Classic 2215 filter. In my tank I have:
5 Odessa Barbs
7 Red Skirt Tetras
1 Blue Gourami
1 Yellow Gourami
2 Angel Fish
2 Cories
1 Bristlenose
1 RTBS
I have plenty of plants, a couple of rocks and a nice piece of bog wood. The water temp is set to 27C. I change about 40% of the water every 3 weeks, the most recent one was 8 days ago, when I also cleaned out my filter (every 3 months). A water test had no ammonia, no nitrite and 30 nitrate. Im not sure why nitrate is that high with the recent water change, maybe i am over feeding? The fish dont seem to be bulging at the belly.
A few weeks ago I noticed my RTBS had a split down its dorsal fin, right to its back. It didnt seem to bother it and a couple of days later I noticed it was joined up again. Last week I noticed again the RTBS had a split dorsal fin, which again had joined back up a couple of days later. I just thought this might be something that happens with this fish, but just now I noticed a couple of my Odessas back fins have a couple of splits in them. Whats the deal with this? How can I stop it? All my fish seem happy, except the Odessas, who are relativelty inactive at the back.
Any replies are appreciated!
