I have been setting up a 5x2x1.5 feet freshwater aquarium for a couple of weeks now. It is still cycling at the moment. I am hoping to have it completely cycled in a few more weeks.
It is semi-planted (5 banana lilies, some java fern, and some amazon frogbit), with a couple large driftwood pieces for decor. All plants are doing well, although the needle-leaf java fern has not really showing much growth yet. I have been doing a fish-in cycling with some hardy species like platies and guppies. Everybody seems healthy and kicking so far.
I don't have the space for a sump, and therefore have had to settle for a Eheim 2217 canister filter, which has been running non-stop.
Once cycled, I plan to add schooling fish to this setup. I want to get a large group of Horadandia Brittani (possibly 30-50), and about 12-18 cardinal tetras. But, I am nervous about whether adding schools that large in size, could potentially shock the tank and cause an ammonia spike. If that is a real possibility, how do you experts suggest I do it? I figured those of you who have kept/keeps large schools must have tackled this issue someway or another? Kindly advise me on how to do it. Also, what kind of growth rate should I expect from the java fern? Seems kinda slow as of now
