[toyota_mini]

hi my gsp is young but is lurking on bottom most of the time water parameters are all go but he has black and gray lines down the length of his body please help! my fish are very important to me they are like my children. if he needs brackish water i would be more than happy to hook him up. any suggestions would be very much appreciated. thanks

Does that mean that he is in freshwater? If yes then I would move him to brackish.

Please read the GSP article in the library.
