Sorry to hear that putting your shrimps with the betta didn't go well. My first betta couldn't have shrimps either as he would go after them. My current betta is ok though, he gets very close and watches them but nothing else?
It would be best to have a filter if you can get one small enough, and if it is adjustable have it on low flow because it is a small tank, the shrimps are fine in flowing slow water,! Are you planning to keep them in this tank long-term or is this tank temporary until you decide where to go next with them? It is possible that some may die from injuries/stress/shock etc, but hopefully they will be ok.
On Saturday I wanted 8 ghost shrimp for my betta (he's in a 12 gallon). Mostly for extra cleaner, while also expecting the my betta trying to eat them. After one night, he ate out the eyeballs of 3 shrimp while the remaining 5 seemed to be attacked but not too damaging. Currently they're in a 2.5 gallon tank, no filter, gravel as substrate, 1 moss ball, 2 plastic plants, and a small castle for hiding. For food I put one algae wafer (in tank right now) and plan to put pieces of lettuce or cucumber after a couple of days.
My question is, do ghost shrimp need filter? I currently have 5 of them in the 2.5 gallon tank. If they do I'm planning on to get a certain sponge filter that's safe for shrimp and small enough to not cause too much current.
Although losing the last killie must have been upsetting, it does now give you a clean working space for getting the parameters sorted and then you can look forward to getting some replacement killie - I love killie, even more than Betta but it is a bit too involved for me so I have avoided it so far!
If your guppies are anything like mine (endlers), fin and tail marks will happen a lot and clear up almost as quickly, they are far too curious/nosey and go into every gap, under moss pads, squeeze behind the filters etc and so mine I have put down to them having just gone somewhere that they have got a small tear or caught on something - behind a filter or too close to a mesh pad etc?
Thanks for the heads up! I left the tank a month without shrimps even though they 'say' you can safely use with shrimps immediately.
I'm not all that happy with it in all honesty, I would use the JBL pro scape again in future as it just isn't going as well this time and although the plants are showing a bit of growth it all looks a bit drab and brown compared to Bertie (the betta) tank which is so lush and green and gets WOW from most visitors. The JBL required 50% water changes twice a week for the first 2 weeks but that extra work was well worth it for the better end result!
Thx blue ridge for the advice, currently my problem is with the tds and hardness of the tank. The endler guppy no longer has a problem with her tail, and sadly the rocket killie has passed away. All of the other fish look fine, and I think the reason my killies have had it tough is due to the hardness being way too much for them. As there doesn’t seem to be a disease with them, my main focus is to get the hardness down before I lose my last 2 😢.
