Days 6-7 | 'Independence' Siamese Fighter Spawn Log | HMPK Mustard Gas Female x Blue Veil Tail Male
It's been a wicked couple of days in the fry tank. Lots of changes, lots of growth.
Removed dad fish from the tank. The fry are now well and truly free swimming and because I'm having some trouble working out a filtration arrangement that doesn't suck the fry into the filter, I thought it best to remove the father on Day 6, when the fry were 5 days old. (This counting between spawn date and hatch date can be confusing, but bear with me. The spawn log has run since the time of spawning, but fry age is given from their hatch date.)
Father was not pleased about this and spent a day or so sulking back in the main tank. It is not uncommon for males separated from their spawns to be depressed for some time, the spawning process is very tiresome, as is the constant monitoring of the young. He is eating well and the fins that the female well and truly shredded are beginning to regenerate. The great stress on parent fish is why fighters should be conditioned before they are spawned. Conditioning means feeding them nutritious foods often. Live foods are recommended, like daphnia, brine shrimp and white worms.
The fry continue to thrive, even in the face of the fairly large water changes I am doing on the fry tank. Many sources say that fry are too weak to withstand water changes at this age, however because the tank they are in is so large, the water changes, though large, appear to be manageable. I add new water at the far end of the tank, away from where the fry are largely clustered together, and they seem to be doing well. The tank currently has 40 liters (10 gallons) of water in it and I am doing water changes of around 10 -12 liters (3 gallons) a day, so 25% water changes. The fry do take refuge under the heater and on the bottom of the tank whilst the change is taking place, but freely swim around the tank once the danger has removed itself.
You'll note if you have been reading previous installments of the spawn log that I thought this would be a small spawn. Well, it's not. It's not a large spawn either. I thought I had between 20-30 fry, now 60-70 seems like a more accurate assessment, there may be even more than that. I have yet to see any significant die off as yet, I found one dead fry today, I suspect that it was caught in the filter.
The fry seem to be eating the JBL NovoTom, though it does seem to leave an oily surface on the water, which I clean off each day. This is probably due to some overfeeding. However the frequent water changes offset that issue and it is important for good fry growth that all fry have access to food all the time.
