You might be able to keep the snowflake for 18 - 24 months depending on the size. Try to get a very small one and be prepared to upgrade the tank or find him a new home in about 2 years. A golden dwarf moray will set you back anywhere from $150 for a very tiny one with no guarantee that its feeding upwards of $250.00 plus. A small snowflake can be had for around $14.00 - $20.00 said:That info really helps shse666! Thanks
