I have found (through trial and error) that goldfish and liptick plants prefer to be watered more often than a lot of other houseplants. Others may have different experiences, but I'm afraid of overwatering, so I tend to underwater, and I killed quite a few of these plants until I experimented with watering them more often. Great results! The biggest thing you need to keep into consideration is that you need a LIGHT mix that drains quickly. A heavy mix will cause them to rot in no time at all. If the soil remains wet over a number of days, it's too heavy. A peat mix mixed half and half with perlite works well. So does a little peat and a little orchid mix with perlite. As as it's free draining, you can actually water quite often without fear of rot.
