As usaul i walk into walmart and check what fish they had. I see a tank of Black Knifes and Royal together. There are about 20 alive in a maybe a bit more than 10 gallon tank. The blacks were about 4 inches and the royals about 5. At the back by the filter there were about 5 dead blacks and about 4 dead royal. It sad that walmart just let that happen. I wanted to buy them all to save them got the evil walmart people but i dont have the tank space... or anything to hold them in..
...thats too bad......
