What size tank will you be upgrading to? TSN, RTC, and TSNxRTC demand HUGE tanks, so they're out of the question, unless you can get a 1000 gallon wall tank by next week. Jurs are sweet fish, some have killer patterns, others are drab. Tigs are beats, but susceptible to "sudden death syndrome" or whatever. Marbled pims are cool though. 2 foot max on them.
