Okay, so bit of a long story, but for background info, I picked them up from a lady I know who had been left with them by her grandson, she didn't know what to do with them and asked me to take them. So I did. There were four in a 60cmX30cmX30cm tank which I read was too small and was absolutely filthy to the point where it stank up my house. I tried water changes and ended up having to do a full water change but left the pebbles in to cycle the tank. Not long after that one of the larger males had a leg chomped off and died and I had to change the water again, this time I removed the pebbles and scrubbed out the tank and started over again. Two are about 15-16cms and are female one is about 18-20cms and male. I currently do a 30% water change daily. This is getting hard to read so I will bulletpoint my questions! ( I will probably have more as I learn more)
* Should I add sand in
* Should I use a filter or just a gravel cleaner
* They seem to be rather picky eaters, they came with a bit of frozen 'axolotl food' from the pet shop, I have also tried bloodworm, earthworm, and liver.. they occassionally eat it or spit it out depending on their mood I suppose
