Hi all, just joined the forum : ) I'm new to aquarium keeping. Over the last 5 weeks I've set a 112 L tank up with sponges in the pump/filter. I have sand on the bottom and a few plants. After running it empty for a couple of weeks, and a couple of good water tests, I added 4 scissor tails. A week later I added 6 pentazona (5 bar) barbs. All look healthy and happy. Will slowly add more in the coming weeks. The scissor tails are very fast eaters and eat all of the food immediately. As the barbs stay around the bottom they don't seem to be getting much food, if any? Just wondering if I need to get food down to them past the veracious scissor tails! Thanks in advance.
