Moving dwarf rasbora from nano shrimp tank

Post by robbo81 »

Evening all
So my 23 l fluval edge cherry shrimp tank also has around 5-6 dwarf rasbora , I shall take a picture shortly for identification.
They have always appeared to be pretty happy in the tank but of late they seem to only ever hang around one corner of the tank and don’t seem to be eating. The shrimp population in the tank has grown massive which I asked about in another post.
Appearance wise they seem healthy enough but I’m thinking of maybe moving them into my fluval Roma 200.
I’m unsure if my Roma is over stocked as I do have a lot of fish in there but it doesn’t look crowded, and it is well over filtered and I’m sure 6 tiny rasbora won’t have a massive negative effect.

As for stock of the fluval Roma 200
20 small neon tetra
14 espie rasbora
4 bentosi tetra
2 sae
6 cory ( sterbai - panda )
1 bristle nose plec small
Red cherry shrimp around 20

Filter wise I have all ponds solutions booster filter for mechanical ( sponges ) then tetra tec ex 1200 filter biohome in every tray , returned to tank via fluval in line uv.
I also have a small double sponge air driven filter in the tank just to keep the shrimp somewhere to graze on.

Just after opinions on adding these small rasbora into a bigger tank.

Thanks all

Rob

hi there. My ph is around 7.5 possibly a little lower. According to the water board we have soft water although I am not able to properly test this

Dwarf Rasbora (Boraras maculatus) do prefer soft and acidic (below pH6.5) water.

Temperatures:-
20 small neon tetra - 21-26C
14 espie rasbora - 23-28C
4 bentosi tetra - 24-28C
2 sae - 22-28C
6 cory ( sterbai - panda )- (Sterbia 22-28C; Panda 22-25C)
1 bristle nose plec small - 21-26C
Red cherry shrimp around 20 - 22-26C
6 Dwarf Rasbora - 20-28C

24/25C (24.5C) would be a compromise for all the fish.

As for stocking the Fluval Roma 200L, then adding the 6 Dwarf Rasbora will put you at around maximum stocking level but a little short on filtration (80%) when all the fish are fully grown.
That's if you are using the Fluval U4 internal filter.

Hope it helps

Hi there. Yes I do keep my tank at 25 oc
And definitely don’t use the internal tiny filter . I’m guessing my filtration is good as I don’t ever have any ammonia or nitrite issues and my nitrates are always fairly low now I’m keeping up with water changes

The Tetra EX1200 is a good filter.

This is my re-arranged media set up.
