its always a treat when substrate spawning cichlids do that.
I'm guessing this was unexpected? And, the intention is not to have these cichlids as a breeding project or something?
- What size is the aquarium?
- Is the pair in a community tank? Or, are they the lone occupants?
- Are all of the fry free-swimming yet?
In the interim, you can feed the babies ground up flake food. When you get the chance, you could purchase a product made by Hikari called 'First Bites'. This is a rich, really good first food source with a very small particle size designed specifically for baby fish to eat. Provide plenty of variety. Your Severum babies will appreciate chopped up black worms, newly hatched baby-sized brine shrimp and mosquito larvae (if you can collect any). Plus, when feeding the parents it's kind of cool to see the babies swarming around to eat uneaten food particles swept out of Mom and Dad's gill rakers.
