I guess the info would help... They are baby cuttlefish, dwarf species from the indian ocean. This particular one has the remnants of his yolk sac plastered all over his tentacles
they are smaller than peas, right now they are in an empty but established 5 gallon, overskimmed, equivalent of an AC150, temp 79 degrees. They are a dwarf species reaching 4" out of the indian ocean, and will need about 30 gallons. If I can breed em, I will be very very happy, they don't live long, and a constantly replenishing supply would be awesome.
