I just noticed that my blue acaras (well actually they were sold as blues but may be Green Terrors as they have orange tail fins and were v. aggresive to thier previous tank mates) have hatched hundreds of fry. They are in their own tank and don't seem to be eating any fry- but what can I feed the fry? I dont have any brine shrimp or infusoria but have tried crushed flake which they don't appear to be eating.
