Hello everyone! I recently acquired a pair of german blue rams (well the male I've had for awhile, the female is new). They have already spawned twice (2nd time last night), but there seems to be a problem. The first set I suppose weren't fertilized (They got some white fungus on them) and I'm worried that these aren't either. AND This morning my male is acting stressed (darting up and down the aquarium wall). I did a 40% water change (it was their day, anyway) and he's still acting that way. He is also fighting with his mate. He ate a bit, but not much. The female is still guarding the eggs and she seems like she is trying to comfort him, but he's not having it. This is the first time he has ever done this since she's been around. He used to do it a lot before the mate came along. Their diet is Hikira Brine Shrimp w/ Spirulina, shelled peas, and Hikari micro cichlid wafers. Water Conditions: ph: 6.6 -6.8 kH: 4-6 degrees (my water from the tap is like 10 -12. my driftwood is a life saver) Ammonia: 0ppm Nitrite: 0ppm Nitrate: 20ppm Temp: 79 -81 degrees Tank is a 30 gallon tall. Running an undergravel filter w/o carbon with an airpump rated for a 60 gal tank and an Aqueon Quiet Flow 20 w/ carbon changed every 5-7 days. Gravel substrate. Tanks mates: 4 neon tetra 3 cardinal tetra More ramshorns and bladder snails than I can count. Heavy planted (my avatar is about 2 months old or more) Java Moss, Purple Cabomba, Temple, Anubias, guppy grass, wisteria The only thing new to the tank is I started using Excel yesterday. I already use flourish comprehensive. Trying it out before I setup Co2 To the point: How do I know if the eggs are fertilized and could the excel be messing with the fish? The male ram is the only one freaking out. His color is good, but he's acting very strange.
