NOTES: Announced as "Semotilis margariscus." Recorded in a 50-gallon tank. Uncertain which clicks are fish -- recordist mentions the staticky clicks seem to disappear when fish are at the surface and seem to be biologic. Much static. Also, mentions the same "daa-daa-daa" sound heard as on MLNS# 116602.
