Hi knowledgeable Fishlorians, Some background: I am still in the pre-planning stages for what to do with my 29 gallon tank. It needs to be cleaned out, seeded, etc. But I was thinking that I could set up either my 2.5g tank or my 10g tank to house just plants while I get my act together with the bigger tank (which may be several weeks, to be honest). I would probably use the 5g tank I'm currently cycling (fishless), but it's sort of inexplicably running too hot at the moment (details here), and I think putting plants into 80-84 degree water might not work out for most plants. Especially as the plants would probably eventually be transplanted into a much cooler tank. One of the ideas I was considering was putting duckweed and anacharis in the plant tank and then feeding it to goldfish in the 29g. I don't know if I'd want to let duckweed just grow in the 29g with the goldfish, since I'm sort of afraid of them just eating it til they die. So my questions are as follows:Is it better to have some fish in the tank, just to maintain a cycle? Maybe some small fish, like tetras? Endlers? Possibly guppies? I mean, are the plants healthier with a cycle?If there are no fish in the tank, how would the water changing schedule go?If there are some little fish in a heavily planted tank, how much time do you estimate the plants buy you in between water changes? That is, how much do they impact the nitrate build up?Without a source of ammonia (fish), the tank shouldn't even start cycling at all, correct?If the tank does start cycling, the plants wouldn't suffer from the tank cycling, would they? I am considering keeping some small fish in there mainly because 1) the LFS seems to always have small fish in the plant tanks and that seems to be the norm, and 2) having another tank with a stable cycle makes it easier to seed a quarantine/hospital tank. Thanks for your help in advance!
