Basically mate everyone on this forum is saying get rid. And I agree. Angels alone need huge tanks because they grow outwards and upwards quite a bit. This tank is not even suitable for coldwater minnows. You need to spend money and get a filter, heater, thermometer and some stock such as neon tetras. BUT YOU MUST CYCLE FIRST. Donate all fish, 100% water change and read the pinned thread on fishless a cycle. If you're going to keep fish, do it properly and learn about them first. This is animal cruelty and I hope to god it is just someone's idea of a sick joke.
