[ATTACH=full]21738[/ATTACH] Hi. Bright green frogspawn been in tank 4 months growing happily. Fine last night. Got home from work today and about half it's tentacles are missing ? I have recently increased flow but not a huge amount. What could possibly be its issue. Tank parameters. Ph 8,3. Alk 9.6 cal 420 mag 1300. Salinity 1.024. Increased last 72 hours from 1.023 ??? Could this be it. ? I don't want to lose it ?
