Cycling new tank

  • We are currently upgrading MFK. thanks! -neo
My other tank has been running for 8 months and I put the media in a week or so ago...
No one seems to know what these arrow sharks are but I read they are in the barb family...

I for several of us are very confused do you mean a bala shark?

Goldfish from an LFS are generally disease ridden and goldfish are in general about the worst fish possible for water quality and cycling. I would be more cocerned about what was left in your tank from them. If you already had an aquarium running all you need to do, well all I do, is put water in get it up to temp run mechanical filtration and then take half/some bio media from the existing tank and put in the new tanks filter. Bam add your fish, keep an eye on quality and make sure nothing spikes but unless you stock it severely the bio should be able to keep up and then grow so there is no concern for buildup.

You trying to house a festae pair in a 40 gallon is a another concern unto itself. I had a breeding pair with the male around 9" and the femal at 6.5" left one day and came home to my divider being knocked down and badly beaten female who died within a few hours. a 125 would be fine for a pair, my male was just mean as most are and my divider to weak.

Bottom line, large aggressive fish + a small tank = bad idea

That is where the :popcorn: comes from because they know the setup you are considering is less than ideal and people will tell you so. I'm not saying any of this to belittle you, but just to help you learn. Nobody starts this hobby knowing much of anything. I certainly didn't and heck since I have only had one tank over the past few years instead of ten and stopped reading and expanding my knowledge I am re-learning a lot of what I used to know. I just want to help you get something that will last so that you don't get frustrated because your fish are always dying. It's not a fun hobby if it ends in death of fish that you come to enjoy.
 
Ammerman thank you for that post...as of right now my tank is fully cycles...I don't plan on keeping the festaes forever, but only watch them spawn a few times and keep the fry...I totally understand a 40 breeder is way too small that's why I just want a few spawns then maybe give the pair to a friend of mines...as for the shark no its not a balance shark...I took them to a pda n they didn't even know what they were but they took them for exchange for a couple small cichlids to keep my cycle going...

what kind of small cichlids? Oscars would go nice with your festae in that 40 breeder!
:ROFL:
 
Only 1 of those 3.5" festae will live to be given away. You need a minimum of 75g if you're trying to establish a pair from a group of juvies that size. My 4" trio started spawning in a 75 but had to be moved when they hit 5".
You're not gonna get a few spawns in a 40br. They are not suited for spawning the highly aggressive species which top out at 12"+.
Personally I'd use a 100g and once a pair forms move them to a 6ft tank with dithers. Or replace the other festae with dithers. But at their adult sizes you'll need a 6-8ft tank
