Hello. I am new to the site. I have been keeping some fish off an over the last 15 years. I recently decided to dedicate my 75 gallon tank to a single fish. I currently have a juvenile Red Tiger Oscar. Tank water is 80 degrees, 0 ammonia, O nitrites, 10 ppm nitrates, and 7.6 PH. Filtration consists of an FX4 can and sponge filters and Tidal 110. I am not sure if I will keep the tidal 110 or keep the two sponge filters. I am feeding Northfin premium cichlid food (2mm) size and some New Life Spectrum Cichlid formula. My goal is to keep this fish for at least 10 years.
