Hello guys, Have had my aquacube 30x30x30cm for 2 months and have 8 baby danios, 6 green tiger barbs and 1 baby ruby shark. We have another tank coming this week twice the size and no desire to get any more fish for a while as we are new to the game. All the fish seem to be doing fine but the ruby shark doesn't seem to eat any thing apart from algae - which I am guessing there isn't much of at the moment. The others feed well on flake food but they also tend to eat his wafers too. I have tried advice found on the internet about putting the wafer in when the lights are off but then I don't know if he's eating either! Was thinking about some bloodworms but i'm not sure if he's just timid? I even tried wilted spinach leaves last night but nothing! Any advice please? x
