Ive had my tank running for about 2mos and i just started really planting stuff. the plants have been setteld in for about a week now. so how long do you normally wait to add the shrimps in? im thinking about putting in some low grade. i only have 2 otocinculus fish and one tuxedo guppy. the guppy will be removed and eventually replaced with some amber color tetras later on. should it be ok for me to put in the shrimps or will i be expecting some spikes in water quality as the plants set in?
