Hi everyone! First post here but been lurking a bit. A bit = half an hour 
I have a 10 gallon tank that only had a feeder fish in it for about a month until the water cycled or what have you. This one's been fine for a few weeks now so I figured it was time to get a couple more fish. Ended up getting two new ones yesterday - a ryukin and black moor, each about 1.5" (the ryukin slightly bigger and wider).
Upon reading some of the posts here it seems like this might not be such a good idea with the amount of waste goldfish like these produce. I tested the water nitrate, nitrite, and ammonium and it all seemed okay but it's only been half a day. Not to mention that goldfish from what I've read can grow larger.
I'm gonna take some of it not all fish back during lunch today. Which would be my best option? ....
1) return the feeder and ryukin, keep the black moor and add a snail
2) #1 but add a few endlers
3) return them all, get a beta, snail, and few endlers
Or .... ?
