the LFS has a 3" juruense cat that i want to get but they said it wouldent live in my hard water(7.8-8) is this true? and if not how hardy are they at that small size? it has one long tail "banner"on top that looks white but the bottom one is gone how long untile it grows back? any other info would be good sence i havent looked into these cats mutch because ive never seen them around before(but i whant one
)also its priced at 70$ but on a certin day of the week all fish are 1/2 price so 35$ is that a good price?

)so far he eats blood worms ,krill, smelt ect but its hard to get him to eat it sence hes at the back of tank and most of it gos right by him when he gets comfy will look for food like a RTC would or will he only eat what floats by? would uping the temp to 84 and feeding him several times a day help his growth?and still woundering how fast that is?
