thanks to a misinformed employee, we have three goldfish and a 5 gallon tank. right now, I do between 20% and fifty% water changes daily to keep the ammonia down and remove any food they don't with our fish net and rinse it. so far, the ammonia is almost zero but it's a tough cycle considering keeping them in such a small tank will leave them stunted.since the employees convinced by parents the small tank could hold fifteen fish, namely goldfish, i've been fighting to get a bigger tank. now, within April, we're getting a sixty gallon tank, 1200mm*450mm*450mm. right now all three are around three inches long (including their tails, two inches while excluding their tails) and I was wondering if the tank size is big enough to accommodate our two feeder and one orlanda goldfish when full grown, and maybe one or two more? or is that pushing the limit?
