Dont want to completely submerge my hand with the incision into any of my tanks but was able to gravel vac the 40B QT because it is shallow and then did a drain and fill on my 90g community tank. Was surprised that there wasnt any real waste or excess food in the 40B so the clown loaches are eating well and eating all the pellets and frozen foods I have been giving them. I know they grow slow so Im trying to get larger sized fish to start but I am not sure how many I should do in the 300. I have read that the larger the group the better. Any suggestions?
Since they are a schooling fish (schooling loaches) and you have a 8’ 300 gallon, my guess would be to go between 10 and 12. This is because they can grow up to like 11” and live like 15-20 years if I remember correctly.
If your 300 gallon was a 10’ tank, you might be able to get away with about 15 clown loaches .
Honestly though, with them growing so slowly and me never seeing any grow above 8-9” in all of my years in the hobby, you might do more while they are young and then sell off the ones that you like the least later on for a decent amount of money!!! Maybe even making back most of your initial investment!!!
I say that but also know with the way you keep fish in such optimal water conditions that you will be the first one to actually grow one to 11” that I’ll be able to see with my own eyes. Haha
Just my two cents….. I’ve owned them many times before and always did about 5 in a 75g but then mine never grew fast enough so I always sold them off when they were about 4” total length .
