Hi aquaman45, E.C. and scott s,
Thank you very much for your response! this really helps me a lot. considering this is my first pair of rays and that there is so much information in the web that you wouldn't know what to believe anymore. anyway here are some additional info:
-I have no water heater. I live in the Philippines so water is pretty warm my thermometer reads 30 degrees celsius (please advise if I need a water heater regardless)
-Nitrate level (0 ppm)
-Nitrite (0 ppm)
-Ammonia (0)
-pH (7.6)
*I used "API Test kit" to get the said readings.
-Aquarium size is a 75 gallon dimensions are 48″ x 18″ x 21″. (This is just temporary until maybe at the end of this year, I plan to get a custom made 8feet x 2feet x 2feet tank)
-Filet is an eheim professional 2 (2028)
-plant in the tank are live plants
-water change schedule is every week (Sunday) 20-30%
-Fishes inside the tank are a Red tail banjar arowana and 2 motoro stingray.
*Arowana (5-6 inches)
*Stingray (4-5 inch disk size)
again thank you very much for all your help! this is very much appreciated!
