Just got an already setup tank someone was selling, stated there was "a" blue shrimp in it, turns out there were five adults and 4 babies. One blue guy bit it this morning, I'm trying to make sure the others make it. 3g tank, plants and sand sub. Water temp was hovering around 66° yesterday, we keep it cold in our house, so i added a second tiny heater, spiked to 78° but stabilized at 74°. Then the blue bit it. So i was inspecting the shrimps and the amano has gotten redder/pinker and what i thought was a gold line down one if the shrimps backs kind of neocardinia-like may be rust?? Velvet?? I just want to be a good shrimp mama but im new to this 😬 its possible i overfed them for a hot second and that could have been what killed the blue. Also i don't have any tests at the moment, please dont yell at me for not knowing water parameters 😅

Added pics of possibly infected mama.

That's not rust disease. 

It has a unique colouration, but that's all it is.

I'd keep the new shrimp at that colder temp of 66F, rather than heat the tank. Shrimp prefer the cold.

Has the tank been cycled?

As per JayC, that is part of its colour, some call it a 'go faster stripe' and it looks really great and I don't see anything to worry about. The shrimp that died may have been the increase in temperature from 66 to 78 as I imagine that happened quite quickly in such a small tank (although they would usually be ok at 78), so may have stressed that shrimp too much! Hopefully the other shrimp will be ok but keep an eye on them. Also as per JayC, the shrimp should be fine at 66 degrees.

Foodwise, you really shouldn't need much, maybe none, with so few shrimps, so if you are feeding bear that in mind, you should just probably feed very little every now and then AS A TREAT as there should be enough biofilm in the tank. You need to revisit this when the colony grows of course. Often shrimp will make a bee line for added food IF they are hungry but show little interest in added food if they aren't hungry as there is enough biofilm.

Welcome to the forum by the way!

Great! That's what i initially thought about the color but i was afraid that the shrimp would get sick and then everyone would go. "Of course it's an infection, its gold stripe disease, rare and fatal if left untreated! Why did you wait!!" haha. i did read jayc's very thorough post and i appreciate him, i guess i just wanted confirmation. Idk how well they were taken care of before the weekend. Let's hope the gold strike carries through to the shrimplets 

 

Thanks again!

Oh and yes the tank was cycled when i got it but im not sure to what degree it was maintained, the woman had young kids and it was being sold cause of upkeep difficulty. I also unfortunately had to do a massive water change bc they dropped 50% of the water out for transport and i read small changes are better

      keeping cinnamon sticks and oak leaves in tank - how long?

      I would add that boiling discourages natural decomposition and would likely break down the antifungals present in the bark, letting the fungus actually grow.

      What nice friends you have! Have you named the new betta yet?

      Betta Water Parameters

      By sdlTBfanUK · Posted

      I had friends round at the weekend, moving furniture around so now I can see the fish tanks from where I normally sit. The only tank that has been running since I moved has had bloody mary shrimps in it and they are fine. It was my betta tank before, and after moving my friends went out and got me a new betta;- As you can see he is ultra healthy looking (pic is of him in the fish store tank) and he has been very active from the moment he arrived and started a bubble nest within an hour of going into the tank. He is about half the size of a fully grown one! He is a bit bland to look at as just white but I went for him as the tank is quite (understatement) dark and so he is easily visible, even from a distance. Hopefully he won't devour the shrimps (the odd baby shrimp I don't mind) but I will have to see on that issue! All the water parameters seem fine aside frm KH which is 6 as this area has harder water than where I was before, but I will gradually get that down using the filtered water (RO) with GH+ shrimp remineraliser from this point, that has no KH and I will just do it gradually over a loooong period as neither he nor the shrimps seem unhappy as it currently is anyway! Apparently the store he came from also sell blue bolt (and some other taiwan bee type) shrimps etc so I will start thinking about setting that tank up (it is situ next to the betta tank) at some point in the near future, though that will be months away even when I do decide to start, as the substrate needs running-in, and the tank will need to cycle etc.

      I see the 2 shrimplets, very exciting and the shrimp in the photo look very healthy! The KH is fine at 3 and slowly dropping because of the substrate, but still in the acceptable range. Not sure about your tank size, other than 'nano' but if you have fish in that same tank (I think I see one in the photo blrred and at the back) I would do 25% weekly water changes (mainly because of the fish) and that will help counter the substrate as well, until the substrate is 'exhausted' of its buffering ability. Use the same kh4 new water as currently and always add the new water slowly, a drip method is best. Obviously you will need to be extra careful when removing the old water that you don't remove any of the new shrimplets........ Try not to change too much though as you may do more harm than good and it looks like everything is actually already going well, visible mating behavour and shrimplets doing well. Hope you manage to get rid of the planaria and that usually involves sizeable water changes in the process so complete that first and from then do the 25% regular water change routine. As the population grows you will need to increase the amount of food but be cautious not to overfeed. The bacter AE should help with biofilm growth etc but it isn't actually a food for the shrimps, though you may see them eating some if it isn't dissolved fully. The scuds are harmless and I would (and did in the past) remove them manually when you see them.
