2 days a go i separated in a 30 liters tank 4 Cory Similis from my group of 11. Today , after i got back from the office i found them spawing . They made a short break for 2 hours , that is when i colected 10 eggs that where deposed all over the tank , on all 4 sides of the tank and 2 on the leaves of some anubias . After 2 hours they stared again and removed another 4 eggs . They're arrownd 12 months old , water temp 25 C, kh 7dh , GH 8dh , ph ~7.5 . The first batch of 10 eggs i separated in a plastic container with an airstone, 1.5 l of water from the tank and a drop of metilen blue . The second batch of 4 eggs i separated in a smaller plastic container with water from the tank, airstone and 2 alder cones .
it took me 3 spawing to learn how to raise the fry past the 4 weeks barrier . in my case they where more dificult to raise compared with the C.Panda fry. what i finde out by trial and error is that an "hands off aproach " works better . the water changes where made trough a small air tube , with a valve at one end to limit the water flow, increasing the time it took to refil the tank . the fry are now 10 weeks old and now share the tank with they're parents. they where raised with mikroworms and tetramin baby . it took them ~ 8 weeks to develop the color patern of an adult C. Similis.
i attached some photos with the fry and one with the tank of the parents.
