i woke up this morning at looked in the tank to see one of my 3white cloud mountain minnows missing!

i looked everywhere for her.in the plants,under ornaments,even in the gravel.but she was nowhere to be seen.so i wondered if the goldfish had eaten her,but there still babies and there mouths are way too small.so i started searching around outside the tank.and there she was ,dead on the carpet

.my heart broke. there one only way she could have escaped.theres on a tiny gap in the lid,about 1cm,for filter wires.somehow she must have jumped through it.i couldnt believe it ,im sooo gutted.

i hadnt even named her yet,but i think i'll call her houdinie(spelt wrong i know).i just dont know how she did such a dead on jump,its unbelievable.so anyway now theres only 2

. i know i need at least 6 and on monday im gonna get them,3 females,2males.but for at least 6 months they'll be in a 10 liter tank (uk liters ,not us liters),with good filter and twice weekly water changes at 20%.do you think this will be okay.i heard they get depressed in groups less than six.and the three of the were doing okay together,so do you think the other two could (i know this sounds stupid but....) die of depression,(or stress of being lonely) before i get more on monday???
