Last November I rescued 9 goldfish (comets, I think) from a bad pond. I learned everything from this site, corresponding with some wonderful helpers for whom I am so grateful . the move was quite an adventure! Started out with a 29G tank, but now have moved to a 50G. The little community ALL survived my beginners lack of experience and seem to be thriving in their new home. I tried some real plants, but alas they do eat them in the end. So I have silk ones now. The tank has 2 70 Aqua Clear filters and the water is very clear. There was hardly a new cycle when I moved them to their new home Now I would love to add 2 new different fish like perhaps another goldfish species and am wondering if any would be compatible? The little community seems very peaceful. Also, I do want to add that even though goldfish have a reputation of being 'very dirty', these are beautiful and seem pretty clean to me Will be very happy for some advice here. THANKS!
