zane Posted November 20, 2009 Report Share Posted November 20, 2009 Hey guys I have a couple dozen bristlenose that breed for me all the time. i have commons, albinos, longfins and peppermints. I have them breeding in 2 separate tanks but ive decided to set up one of my 2 foot tanks just for the fry to grow out in (no other fish). problem is... at the moment out of 100 fry that i get at a time, only about 40 actually make it to juvi size =(. (got some at about 3cm now). Water chemistry is pretty good i check it all the time. Im thinking maybe i should set the grow out tank up as a heavily planted tank with an undergravel filter? that way all the waste would get sucked straight out and not sink into the gravel? or is that a bad idea? what substrate would you recomend for bristlenose fry? should i try and keep the bigger fry away from the smaller fry? what plants are the best? there will be heaps of bogwood and driftwood in the tank and a sponge filter. temp will be at 27degrees. have i missed anything important? i really want more of my fry to live =( Link to comment Share on other sites More sharing options...
Happy Posted November 20, 2009 Report Share Posted November 20, 2009 personally, i have had the most success with no substrate, lots of small water changes being sure to suck out any detritus left on the bottom each time. Bulk driftwood is good. hth Link to comment Share on other sites More sharing options...
AussieCanadian Posted November 20, 2009 Report Share Posted November 20, 2009 Personally I put all my BN fry in a 4 foot tank to grow out, again with a bare bottom and lods of driftwood. I feed Zuchinni and Softened Sweet Potato earlyt in the week (Monday / Tuesday) and do a 30% water chage Wednesday night and another 15 -20% waterchange on Sunday night to just to be sure the water quality stays high as BN fry are a little bit fragile at the best of times. My filtration consist of 3 large sponge filters and a small internal filter. These are squeeeesshed out every water change. My survival rates are quite good unfer this regime. Under gravel filtration is good over along period of time once it settles in however to convert to undergravel filtration at this stage would most likely cause greater problems with survival rates. Just my opinion perhaps others that use under gravel filters can provide a little more information regarding thier benefits and draw backs. BN fry also need a little protein occasionally i will put some spectrum in the tank and let them eat that for a day to chagne it up. Algae wafers are great staple but young fish need a variety to grow out and develop. Hope this helps. Matt Link to comment Share on other sites More sharing options...
