Acclimating a guppy to saltwater 😁

I have a 6 gallon fluval edge that I have converted to a reef. My goal with the tank is to have mostly coral and inverts however I wanted to have one fish in the tank as well.

First I put a clown goby in the tank and it died due to a scale disease. After that I decided to put in a clown fish in and it then died due to velvet. So after the fish both died I started having flash backs of my old tank and how much money I had lost on fish. Sometimes it was ich, sometimes it was because they would not eat other times it was a sneaky serpent star. Needless to say lots of money lost.

So I decided to go a different route. I had known that there were several fish that could make the transition from fresh to saltwater such as Molly's and puffers. I had remembered hearing guppies could as well but it was a little more difficult.
A guppy would be great I thought, they are $3 and attractive as well as small.

I went to the LFS and got a guppy that I liked. The LFS looked at me like I was nuts cause they had not heard of this being done with guppies before only Molly's.

Took the little guy home and began setting up his home for the next three days.

The set up is a small bucket with two liters of fresh water, a heater and air pump for agitation. I mixed 3 liters of salt water at 1.040 and set up a drip line dripping at one drop every 20-30 seconds.

I'm at about 36 hours and the guppy is still looking good.
He is eating flake food and is calm. Salinity is currently 1.009 and rising.

For me this is alot of fun and very interesting. I'm excited to bring him over to the marine world and am interested to see his behaviour in a reef.

Here are some pictures so far and I will keep the post updated.

Keep us posted. I have heard it is possible not seen it done. Maybe run the salinity on the low side?

My tank is between 1.025-.026 I don't think that's on the high side for a invert/coral dominant tank?. The fish will just have to adapt if it is I suppose. The drip is extremely slow it may even take 4 days not the 3 days I planed for. Evaporation will also play a factor so I don't want to change the drip rate.

Some lfs I have seen run as low as 1020. That can be hard on coral but 1022 probably isn't so bad and might be more attainable. Either way this is going to be cool to see how it goes.

So far it has been a success. Over the three days the guppy didn't even seem stressed. I brought him up to 1.025 then put him in my tank. It actually looks like it belongs and the lighting really brings out the leopard pattern of his body. Here is a pic. Can't wait to see him in the long term

Many years ago, I had a small group of Jewel cichlids (Hemichromis bimaculatus) I acclimated to salt water. Cichlids are relatively easy. Many cichlids actually grow faster in salt water than in fresh. I gave these Jewel fish to my friend at a LFS, who used them to cycle tanks. Mollies are already salt water fish. I've never heard of guppies switching to salt.

Very cool.
He seems to be doing well, seems aggressive likes to run up and down the glass going after his reflection but that is subsiding. He ate flake in the white bucket during the acclimation but have not got him to eat in the SW tank yet.
I'll try tonight.😀 Overall going well.
 
Just wanted to update. The guppy is still not eating but seems to have lots of energy. Maybe he is grazing the rocks at night time. I'll have to keep trying and wait, maybe try a few other foods.
 
If it's not eating....this is not working !....I had guppies as a kid and I don't recall having any fussy eaters....
 
Got him eating a different flake food tonight�� and it is common for fish not to eat when they are in a new environment. More then likely it was the food I was giving him.
 
This is my last update unless something dramatic changes. Guppy is doing really well. Looks very healthy and no odd behavior. Here is a better picture. If anyone else does this let me know.😁
