I used 5 gallons tank..bought a male betta from LFS becoz old one died of fin rot:-(..
and female betta was full with eggs..thats why i got the new one quickly..
kept the male in the tank and female in the jar and placed the jar inside the tank..
male started to attract female and he started building a nest..
next day i put female in the tank..for some time he chased her..fins got torn..so i got scared becoz previously lot of bettas have died of fin rot inspite of medications..seprated them again..
next day the nest was bigger and again i tried leaving female into the tank..and this time success..
The Nest
Female Betta but it has torn fin but belly full of eggs
Male and female
Afterwards separated the female..kept her in clean jar and added salt and medicine..
The male started watching over the eggs..but wen i woke up next morning he was not well and acting strange..he was not eating eggs but he was kind of struggling..and had lost his color and he was destroying the nest..i so took him out & kept him clean jar and added medcine..but he was not feeding..He died after half an hour..
By this time about 30-50 eggs had fallen down..then i googled to check how save other eggs..i read that wen fry hatch they fall to bottom and male picks them and puts them back to nest..Without male, If the depth of water too high they cant swim up and they die..
So used a plastic lid and slipped it below the nest gently and there was half inch gap between nest and bottom of lid..so the if the fry fall down they just hav to swim short distance up..and also i added antifungal medicine.
Picture is not so clear..but thats lid with black specs(fry) and u can see some fallen unfertilized eggs too.
Today is the third day...and i see some free swimming ones and many are still vertical and have yolk sac..hopefully tomorrow all will be in free swimming stage..then i will start infusoria
Sadly these fry have become orphans..both parents are dead now..please tell me how to prevent these deaths & save bettas...lot of them hav died of fin rot..i used medicines,salt and clean water and 3 day water change..
Iam new to this hobby..if there are any mistakes about my methods please let me know.
