very beautiful fish dixon!!!! the fifth pic looks like those two caribes are about to start a fight, i really like your mixed shoal!! is the second serra pic a baby bluee diamond rhom??? if it is its showing amazing color very early
the pic of the red belly next to the caribe, my friend bought 15 redbellys at 1 inch, he started doing pills and about 13 died
he called me up i came over and i checked his water , ammonia was sooo high! so i took his two fish because he obviously couldnt keep them alive with all the pill popping, so that night one red died, the other looked very tattered up and unhealthy, i put him on a diest of sinking pellets (hikari) and to my suprise he loved pellets, now hes pushing 5 in a half inches and holds his own really well, my caribes never mess with him, hes a great fish, i still have him so hes not old scool but my friend no longer has him lol.
the other is a big buch toothed tetra that died recently... not a piranha but watever lol.
