java fern toxic?

Your pH is fine. The pH does not matter a bit to the fish - they cannot read external pH.

The fish you have is from an estuary or bay - the area where waters rivers, streams, bogs and marshes flow into the sea, with large enough tidal mixing areas to have daily and seasonal variation in water hardness (primarily calcium and magnesium ions content), alkalinity (mainly carbonate and bicarbonate ions), salinity (sodium and chloride ions), and in TDS (total dissolced solids, meaning all the already listed ion plus lots of other ions). Your fish was likely born and grew in such relatively high TDS, high alkalinity, high hardness, and detectable to high salinity, and relatively high TDS - in short, water which is intermediate between routine freshwater and seawater.

srry could the calcium in the crickets kill him or was it something else?

If you're loading crickets with calcium and feeding them to the fish then yes, it could have killed it. Neat calcium can 'ossify' (go hard) and cause blockages, or increase the KH of the fish's blood so high that the osmoregulatory system fails.

Slight ammonia might have killed it, but is unlikely if the other fish were ok.

Java Fern is mildly toxic, but only if eaten. (Silver Dollar spp will very rarely eat it, but Scats will).

Dont worry about pH. Anything between 7and a bit, and 8.5ish is fine for brackish water.

my ghost shrimp is gone so i think it could be possibal that he choked on the shrimp but i am intending on only feeding the new one hikari freez dried krill i am getting another filter since there is going to be alot more amonia and toxins when i get the other fish in and the small filter i have now and my mangrove seedlings probably wont be able to get rid of it all i agree with the calcium related death so i wont be feeding calcium rich crickets anymore

Krill is not a good staple food for any fish. Filters do not remove ammonia & toxins--water changes do.

biological filters get rid of most of the amonia and toxins and i will be feeding them krill and silversides or later on floating pellets

Please explain what toxins biological filters remove?

Please explain what toxins biological filters remove?

there are no toxins in my tank except amonia and nitrite the fish waste i remove with water changes and my mangrove seedlings with extremely good root systems i got from ebay should help me to remove nitrate and waste until i do a water change every other week and the filters are both biological and chemical and my aquarium sand is a type of buffering coral like live sand any other toxins i would remove with a water change my archer died from calcium poisoning and from possibaly chokeing on my ghost shrimp

java fern?
jjaaarrrrvvva fernnnnn ?
what makes you think that it is toxic to archers?

I agree--it is not toxic to fish. But this thread is getting old...
