Alright I just got this from someone who was tearing down their salt water tank. Nothing seemed very healthy in the tank but I'm gonna try to save em. Anyways I'm pretty sure the big one is a carpet that is just unhealthy... I just got him and put him under my 150 watt halides in my 125 gallon. His previous owner had very poor lighting. Anyways as far as bringing him back to health... Good lighting and make sure hes fed every couple days right? He is sticky to touch which is a good sign as far as I understand. Anyways the funny headline...... "are you my daddy"? Look at the picture of the little baby.. is he just a smaller carpet? How the heck do I take care of him?
