Re: Panda cories spawned... on rocks!

Yannick i don't try to raise large numbers, and C.Panda have eggs with >98% hatching rate so i'm happy with what i get left from them. - i've used 2-3 spawing mops but still found egss eaten in the mops , i've seen that keeping the fish very well feeded (especialy with live tubi) will reduce the egg...

Re: Panda cories spawned... on rocks!

Pablo , 10-15 eggs usually also, depends on some factors like age of fish , food they get , how many fish in the tank , my C.Panda group, ( witch i keep alone as all the cory i try to bread) , are terrible egg eaters , the fish that don't participate in the spawning , are busy munching on them . whe...

Re: Panda cories spawned... on rocks!

it's to complex to predict when they will spawn again , (factors like : food , age , water change , atm pressure, etc), you can try to trigger them or let them do their thing. for easier eggs colection you can use a spawing mop . i use some anubias floating plants ,and my Corydoras Panda like to dep...

Re: Fishroom Air

-pressure formula = height of water column [m] x water density (mass) [kg/m^3] = X kg/m^2 -there are online convertors to transform pressure kg/m^2 to psi , atm , MPa . -so you can start from the total height of water column and find out the needed pressure or from the known pressure the pump can de...

Re: Trying to identify illness on Corys, white fungus-like?

wellcome to planetcatfish. from the pictures with Corydoras Panda i would definitely say it's an external parasite ! you should try to identify what type of parasite so you can chose the proper medicamentation. JBL has Gyrodol Plus and Aradol Plus for external parasite infections. i would also try t...
