With so many now I found this the easiest way...I now have a spreadsheet with all the fish totals in there, which then adds them up for each species, each tank and overall quantities.Underneath all these calcs I have the last date I observed the total amount of each species per tank.Hopefully that makes some sense.So in answer to your question yes, but like Lunar Jetman not daily, used too, but now that would take too long
As for Kuhli loaches they are a nightmare to count. I have a total of seven in the large aquarium, plus five Java Loaches. I see the Java loaches all the time, as for the Kuhli's I never know where they are from day to day, the most I have counted at one time is five, but they are very elusive. At this stage I plan to get more Javas and maybe a few more Kuhlis will be added, as I know the more you have the more you are meant to see them, not sure they know that though! I am currently swapping some fish around so will need to update my xls.
