A combination of reasons has likely led to the problem:
* temp having dropped from ?25 to 19 (even if the problems are only manifesting as it's been brought back up to the required level);
* angelfishes not having been quarantined (?);
* added bioload affecting water quality (? increased ammonia, nitrite and nitrates, even if broadly within safe range - what test kit are you using and what are exact readings?)
* potential incompatibility of clown loaches, angelfishes, swordtails and other stock (eg larger fish behaviourally, angelfish intimidating smaller fish to extent of them dying) - check out https://www.seriouslyfish.com/species/pterophyllum-scalare/ and https://www.seriouslyfish.com/species/chromobotia-macracanthus/ and https://www.seriouslyfish.com/species/xiphophorus-hellerii/

Small daily water changes and thorough gravel cleaning would do no harm and potentially help considerably.
