Orange Medaka Rice Fish Eggs and Fungus

[Erick Henry]

I have had some rice fish for a week or so in a small established pond containing a single endler and 20 or so rice fish. Several of the females are producing eggs on a daily basis and distributing them or the mop and hyacinth etc. Last night I noticed “ hairs” growing off of several of the eggs and I removed them from the mop. Does any one have advice on reducing or eliminating this issue.   below is a brief description of the tank. Are their issues with drift wood, dirted tanks, or found plants in this set up..? 
 

I have a dirted “tank” with a large stone maybe 15 lb on the bottom and some drift wood planted in substrate is some narrow leaf valasineria. Floating in water is hornwort. In a basket I have 2x lotus tubers and some misc pond plants form a local lake ( 1 is eastern water chestnut- 1 is a mystery..) floating loose is water hyacinth and some frog bits ( I think) .. hope this helps. I attached a link to an older video post of more of the pond.. pond is ceramic planter about  20” tall and a 20” diameter. Had a hole I plugged with Aquarium Safe Silicone and some plastic cutting board..

I was trying to leave the mop in the pond and not remove it. Methblue cannot got in a fish tank only a breeder box for egg hatch out correct..?

You can use it in a pond or breed box I would add  one teaspoon for 30 gallons in a pond it won't be as effective at that level

I really like API fungus cure or pimafix, but it is hard to get currently. Try to raise temp and then methalayne blue next time.

I keep an extra 3 gallon bucket with my "alternate" water hyacinth.  if you just switch out the water hyacinth, you could put the methalayne blue in the bucket (or other container) without having to dose the pond.

I use methylene blue also but separate the eggs from the mop or roots. I just use a cup and leave the eggs in there with the methylene blue solution and I get a good hatch out of it. 

Some people even performs a water changes for the cups holding the eggs to keep the water clean.
