invertebrates?

[Luis Taveira]

All my invertebrates (crabs, sea stars and shrimps) die in a week, i want to know what happen, the water was ok. My fishes (yellow tang, coral beauty and pygmy angel, tomatoe clown, engineer goby). Please, can someone tell me what happen?

I would think that having 5 fish, especially what they are, is way too much in your 29 gallon tank. I think your bio load is way too much. I would be willing to bet that your amm., nitrites, and nitrates are very high. Inverts cannot handle high amounts of any of that. When you say your water is OK, what have you tested for and what are the results?

I tested my water last friday and the amm, nitrates, nitrites, salinity, all was ok. I have a wet/dry filter for a 75 gal. tank so that my water can support all those fishes. I have been with those invertebrates for 5 months without problems and last week my crabs began to die and yesterday my cleaner shrimp and the sea stars die.

I dont know why your inverts are dieing but I suggest you cut back on the fish especialy the ones that are reccomnded for 75 gallon plus tanks. They dont have enough room and WAY to high of a bioload. And a wet/dry is a nitrate factory, not a good filter ... protien skimmer plus refugium is WAY more effiient becuase it gets rid of nitrate aswell.

in a 29? oh my....

Also the issue is not your water capacity, it is the question of area. I can put a tang in a soup pot hooked to a 1000G sump and it will not make a difference, he needs more room.

Will all be pretty irrelevant in the end, if and when the stress issues start, the fish will either die of stress or aggression. As far as the inverts go, it is even possible that the fish are doing them in

As for the inverts, acclimation is the likely culprit, you say in one line they have been with you for 5 months and the next is they die in a week. The one week is pretty typical of inverts that have acclimation issues. Are the snails just tipping over?

Sea Stars: probably not enough tank for them..
Shrimps: predation due to tight quarters and the angels are getting them?

What are the actual water parameters?

Also, there are other two things you need to check for as I encountered last time all my inverts died. First, test for copper, really small amount still enuff to kill them. Second, tray voltage in the water also can kill inverts.
