new discus tank ordered!!!

[greenphantom1994]

finally ordered my new tank today, for delivery next week. jewel rio 300 4ft long 2ft high 20' width (350litres). ive gone for a high quality internal filter, I may even have 2 internal filters for heavy filtration of the tank. hope to make this should be the perfect home for my discus. going for a lightly sanded bottom with driftwood, rocks and a small selection of plants. one thing I would really love to add to my tank is a teacup stingray. ive seen many videos with them in discus tanks, whats your guys opinions? also, could someone tell me what 350l equals to in gallons?

thanks bud. hopefully someone can shine some light on my stingray question.

[sdrexler078]

I know most sting rays need large tanks. 230 gallon being the smallest for 1 ray is what I've read and if the discus are adults they should be ok but it's taking a risk like with any other fish

I personally wouldn't keep a ray in anything less than 200 unless it was for quarantine before going in bigger tank
