Thats not too bad IMO. Depending what you want to keep. As long as its not a really acidic fish. I moved this tank about 6 months ago. Before that I had a 7.4ish pH for about 6 years. I don't pay much attention to pH as long as its in a decent range. I just tested as I couldn't remember my new water levels, but my tap is 7.2 and this particular tank is 6.8.
Total stock in this tank is 6 boesemani rainbows, 6 panda garras, 12 golden pencilfish, 6 rosey barbs, 8 emperor tetras, adult caecilian, and eventually about 8 swordtails. There are 3 swordtails in there now and I think there are like 5 I haven't been able to catch out of the other tank lol.
