Soklom Tong, First of all I apologize for not responding sooner but I have been out of town on business. I have been told in some of the forums that it could be an iron deficiency or lack of nutrients. I am hoping that it is a lack of nutrients as I am down to four fish now. I plan on adding several more over the course of next week. Also, we have had extremely hot days and I think the sun has affected them also. I hope that over the next week or so that I can get the plants to turn around and start looking better. Thanks for the comments.
