i emptied and cleaned my pond yesterday, my god it was hard caching my 2 bass and tandanus catfish, took me over 2 hours. all the other fish were easy to catch because they were much easier to see (goldfish and koi).
my bass are about 10 and 8cm, and the tandanus about 20cm. natives ive had in the past include 2 silver perch, a murray cod and another bass. the 2 silver perch were doing good for a while with the single bass, but all of a sudden one of the perch went on a psyco attack and killed the other perch and bass, and injured 2 of my koi. he ended up jumping out, and i recovered him but he ended up dying. the murray cod refused to eat anything i gave him, from flakes to pellets, bloodworms and even live guppy juviniles. he was getting skinny so i put him in my guppy tank to see if he would eat some fry. a few days later he was eaten by an apple snail.
im going to try the murray cod again after i go to malaysia in summer. and ill try to get a healthier one.

these fish were only in this tank for a few hours while i cleaned the pond, and they were rather stressed at the time.
