Waiting Period

Question
QUESTION: I have an established freshwater tank of 28 gallons with three long tailed rosy barbs, how long do I wait between adding fish?

ANSWER: Hello Raul:  Usually just a couple of days to a week.. depending on the water chemistry.  If the ammonia is at zero then add in new fish but do so a few fish (no more then 4-5) at a time.  dave

QUESTION: Thank you for the answer.  One other question I have is, which are the hardiest freshwater fish?  I have 3 long tailed rosey barbs right now because I have had very good success with them before.  Haven't had great luck with guppies, mollies, or dwarf gouramis.  Are there any you recommend?

I would appreciate any suggestion.

Answer
Hi Raul:  Maybe you could do an all barb tank.  They come in so many varieties that when mixed they make a beautiful tank.  I am quite fond of the green tiger barbs, the golden barbs, and the rosy barbs.  The albino tiger barbs are very nice too.  You can check out eels too.  I love my eels.  A shoal of Cory cats a unique plecostomus such as the blue phantom, danios giant danio, rasboras, etc... would all be goo choices too.  dave
