I’ve had 9 ember tetras in a 10 gallon tank for months now with a betta. I’ve been noticing my bettas fins are very frayed. At first I thought it was the driftwood, then the coconut cave, ext So I took it all out. Today I noticed for the first time that the embers nipped my bettas fins like 3-4 times but at feeding time. II was so upset I was going to take them back to the store, but I can’t catch them at all, impossible. I tried for 30 minutes and I couldn’t get them. So I’m trying to get a black water effect To reduce stress and darken it up a bit, I have cattapa bark and almond leaf to do this I also have hornwort plant coming in the mail to really add greenery and hiding places in addition to the low tech lights I do have. Do you think feeding the embers twice a day instead of once can reduce their nipping around feeding? The betta gets the food too so that why I only have been feeding once, but I can reduce it and feed more often. Getting another tank is not an option right now, any other suggestions? I really don’t want my lovely betta to suffer and be picked on, but I’ve never seen them do it and when I did it was around feeding time, his fins show that it’s been happening enough to fray them though.
