Is it possible that Bronze cory’s may kill my little fella’s?
I’ve got 4 cory’s, 3 guppies and 8 CPD’s/Zebra Rasboras in a heavily planted 100l but I can only see 2 happily chasing each other around and haven’t seen any more in over 24hrs not even at feeding time.Well its definately heavily planted and it wasn’t the cory’s its the nitrite spike I mentioned in t’other post they ain’t dead yet but only 2 of them seem untouched by the problems. I’ve got the nasties right down with latest test so I’m hoping they’ll perk up…
I’ve been a silly boy again!!!!!!!!!!!!!!So are they all still alive or do you think only two have made it? Sorry to hear if its the latter. :cry:
Well I lost 2 so I still have 8 CPD’s/zebra’s (think only 2 zebra), the spikes are settling since I added a 2nd filter my ammonia is trace and nitrIte is less than 0.25mg/l with a 10% change everyday so I’m still giving myself a daily kick in the shin so that I may learn.
The Danio’s are very outgoing & cory’s are laying eggs all over the place so maybe they like really poor water??? :wink:CPDS are quite sensitive fish. They like stable mature water, no spikes. Now everything has settled I’m sure they will be breeding in no time!
BREEDING?? Just trying to keep them alive for the mo’, I added an extra filter to speed things up so now there’s a Fluval 2+ and a sicce shark both turning over 400lph. The plants are growing wild & this mornings test revealed 0 ammonia, 0-possible trace of nitrIte and nitrAte was 0-5ppm.
I’ll give it a few more days then I’ll start clipping away some plants but for the minute they’re helping me out too much to worry about the aesthetics of the tank
you’ll be surprised. Once settled they soon get on with spawning…and then eating all the eggs and fry! :lol:

not to really hijack the thread…but doesnt it seem counter productive that CPDs eat their own eggs/fry?
it certainly does but you tell them that! :lol: I’ve found in very heavily planted tanks fry do survive but only a few. You sadly need to remove the adults/or eggs once spawning has taken place to get any reasonable numbers of fry. The good thing is they are VERY easy to spawn
Ferreter, try reducing the water changes. I also breed corys and noticed that frequent water changes cause spikes. I would do the changes every 2-3 days. That will give the bacteria in the filters a chance to multiply faster. I too like to use 2-3 filters in my tanks, but I use home made sponge filters unless there is a reason to use another type.
M. clausen – It may sound strange but have a look at their natural habitat. Their food sources come and go, if they eat their own eggs and fry it gives the parents a food source for the times when they don’t have any. In the wild enough fry grow up to keep the species going, it seams like a workable system to me.
